Planning overviewThe Symmetrix DMX-4 system is composed of one system bay and multiple storage bays. Figure 1 on page 22 provides a front view of the exterior of a Symmetrix DMX-4 configured with one system bay and eight storage bays.
Figure 1 Symmetrix DMX-4 nine-bay configuration
This section provides an overview of the physical details related to planning an installation of the EMC® Symmetrix DMXTM system. It describes the necessary installation details performed by EMC personnel and outlines customer responsibilities.
Presite planning sessions with EMC
The Symmetrix® DMX-4 system is designed for installation in a properly equipped computer room that provides sufficient physical space, controlled temperature and humidity, proper airflow and ventilation, proper power and grounding, system cable routing facilities, fire equipment, and so on. Although a raised floor is not required, it is recommended.
One or more planning sessions with your EMC Systems Engineer and EMC Customer Engineer may be necessary to close all the details related to installation.
Table 1 on page 23 lists the responsibility summary at the first planning session.
EMC Symmetrix DMX-4 Physical Planning Guide
Physical Planning
When planning the installation site for your Symmetrix DMX-4 system, meet with your EMC representative to complete the presite plan. The computer room must be prepared to accommodate the DMX-4 system’s physical, environmental, and power requirements for proper operation. Physical, environmental, and power requirements planning highlights are described below.
Planning physical requirements
“Physical data” on page 48 provides overall system dimensions and weights for the Symmetrix DMX-4 system bay and storage bay.
Note: The DMX-4 system has one system bay and from one to eight storage bays. When fully configured, the system bay weighs approximately 1,626 lbs (737.5 kg). A single storage bay with 240 disk drives weighs approximately 2,422 lbs (1,098 kg). Table 13 on page 49 contains information on weights of various configurations.
The customer must make sure the site meets or exceeds the specifications listed for both a nonraised floor and raised floor environment as described in“Floor load-bearing requirements” on page 25.
Planning environmental requirements
“Environmental data” on page 50 and “Power and cooling data” on page 54 provide environmental requirements for the Symmetrix DMX-4 system. Environmental requirements for the system before it is installed, and during operation and storage are explained.
Note: Follow the acclimation process to prepare the DMX-4 system for the data center as described in “Environmental acclimation” on page 50.

Planning power requirements
Chapter 5, ”Power Requirements,” provides power requirements for Symmetrix DMX-4 system bay and storage bays.
Note: Before delivery, the customer must supply and install the required receptacles on two separate power distribution units (PDUs) for zone A and zone B power for the Symmetrix DMX-4 system bay and each storage bay.
EMC Symmetrix DMX-4 Physical Planning Guide
Physical Planning
Symmetrix DMX-4 system presite considerationsThe following are considerations that must be taken into account prior to the installation of the DMX-4 system at your site:
◆ “Fire suppressant disclaimer” on page 25◆ “Floor load-bearing requirements” on page 25◆ “Transportation and delivery guidelines” on page 28◆ “Data center preparation for DMX-4 system delivery” on page 28◆ “Environmental acclimation” on page 29◆ “Layout and space recommendations” on page 29◆ “System host cabling requirements” on page 29◆ “Remote support” on page 30
Fire suppressant disclaimer
Fire prevention equipment in the computer room should always be installed as an added safety measure. A fire suppression system is the responsibility of the customer. Care should be taken by the customer when selecting appropriate fire suppression equipment and agents for their data center. Your insurance underwriter, local fire marshal, and local building inspector are all parties that should be consulted in selecting a fire suppression system that provides the correct level of coverage and protection. EMC designs and manufactures equipment to internal and external standards that require certain environments for reliable operation. EMC does not make compatibility claims of any kind nor does EMC provide recommendations on fire suppression systems. However, if a high pressure gas system is used, EMC does recommend that storage equipment not be positioned directly in the path of the gas discharge stream so as to minimize the forces and vibration during the discharge.
Note: The previous information is provided on an “as is” basis and provides no representations, warranties, guarantees or obligations on the part of EMC Corp. This information does not modify the scope of any warranty set forth in the terms and conditions of the basic purchasing agreement between the customer and EMC Corp.
Floor load-bearing requirements
It is recommended but not required that the Symmetrix DMX-4 configuration be installed on a raised floor.
If the system is installed in a raised or nonraised floor environment, customer must ensure that the subfloor or site floor, respectively, is capable of supporting the system weight specified in Table 13 on page 49.
Symmetrix DMX-4 system presite considerations 25
26
Physical Planning
If the system is installed in a raised floor environment, customer must ensure that the raised floor is capable of supporting the system weight. EMC recommends the use of 24 X 24 inch heavy-duty, concrete-filled steel floor tiles. If different size or type of tile is used, customer must ensure that the tiles have a minimum load rating that is sufficient for supporting the system weight. To ensure proper physical support of the system, the following requirements, which are based on the use of 24 x 24 in. (61 x 61 cm) heavy-duty, concrete-filled steel floor tiles, must be complied with:
◆ Floor must be level.
◆ Floor tiles and stringers must be rated for a minimum static load of 1,600 lbs (725.7 kg) based on two casters of 800 lbs (362.9 kg) each per tile.
◆ Floor tiles must be rated for a minimum of 1,000 lb (453.6 kg) rolling load.
◆ Floor tiles and stringers must be rated for a minimum static ultimate load of at least 3,000 lbs (1,360.8 kg) per tile.
◆ Floor tile deflection must be minimized with additional pedestal mounts.
◆ Do not position the system bay or storage bays with more than two casters on a single floor tile.
Note: Cutting tiles per specifications as shown on Figure 4 on page 59 will ensure the proper caster placement.
◆ Use or create no more than one floor tile cutout that is no more than 8 in. (20.3 cm) wide by 6 in. (15.3) deep in each 24 x 24 in. (61 x 61 cm) floor tile.
◆ Floor tile cutouts will weaken the tile. Therefore, at least one additional pedestal mount adjacent to the cutout of a tile is recommended. The number and placement of additional pedestal mounts relative to a cutout should be in accordance with the tile manufacturer’s recommendations.
◆ Care should be taken when positioning the bays to make sure that a caster is not moved into a cutout.
◆ Ensure that the weight of any other objects in the data center does not compromise the structural integrity of the raised floor and/or the subfloor (nonraised floor) of the data center.

Customer must be aware that the load-bearing capacity of the data center floor is not readily ascertainable through a visual inspection of the floor and that the only definitive way to ensure that the floor is capable of supporting the load associated with the Symmetrix DMX-4 storage system is to have a certified architect or the data center design consultant inspect the specifications of the floor to ensure that the floor is capable of supporting the system weight specified in Table 13 on page 49. Customer is ultimately responsible for ensuring that the floor of the data center on which the Symmetrix DMX-4 system is to be configured is capable of supporting the system weight, whether the system is configured directly on the data center floor, or the system is configured on a raised floor supported by the data center floor.
Failure to comply with these floor-loading requirements could result in severe damage to the Symmetrix DMX-4 system, the raised floor, subfloor, site floor and the surrounding infrastructure should the raised floor, subfloor and/or site floor fail.
NOTWITHSTANDING ANYTHING TO THE CONTRARY IN ANY AGREEMENT BETWEEN EMC AND CUSTOMER, EMC FULLY DISCLAIMS ANY AND ALL LIABILITY FOR ANY DAMAGE OR INJURY RESULTING FROM CUSTOMER’S FAILURE TO ENSURE THAT THE RAISED FLOOR, SUBFLOOR AND/OR SITE FLOOR ARE CAPABLE OF SUPPORTING THE SYSTEM WEIGHT AS SPECIFIED ABOVE. CUSTOMER ASSUMES ALL RISK AND LIABILITY ASSOCIATED WITH SUCH FAILURE.

EMC Symmetrix DMX-4 Physical Planning Guide
Transportation and delivery guidelines
Symmetrix DMX-4 systems delivered within the United States or Canada travel by air-ride truck. Each Symmetrix DMX-4 system is shrouded by custom-designed shipping material, crated, and palletized.
Symmetrix DMX-4 systems delivered internationally normally involve air freight. Unless otherwise instructed, the EMC Traffic Department arranges for delivery directly to the customer’s computer room. To ensure successful delivery of Symmetrix DMX-4 systems, EMC has formed partnerships with specially selected moving companies. These companies have moving professionals trained in the proper handling of large, sensitive systems. These companies provide the appropriate personnel, floor layments, and any ancillary moving equipment required to facilitate delivery.
Data center preparation for DMX-4 system deliveryThe following are considerations that must be taken into account prior to the delivery of the DMX-4 system at your site:
CAUTION!Inform EMC of any labor union-based restrictions or security clearance requirements prior to delivery.
◆ Weight capacities of the loading dock.
◆ Weight capacities for tailgate.
◆ Length of covering required for floor protection.
◆ Weight capacities for service elevator if delivery is to another floor.
◆ Equipment ramp needed if the receiving floor is not level with computer room floor.
Note: All portions of the bay shall clear ramp and threshold slopes up to 1:10 (rise to run ratio), per Code of Federal Regulations – ADA Standards for Accessible Design, 28 CFR Part 36.
Physical Planning
Environmental acclimation
The DMX-4 system requires a period of time to become acclimated to a data center environment. Follow the acclimation process to prepare the DMX-4 system for the data center that is described in “Environmental acclimation” on page 50.
Note: Temperature and humidity values experienced by the system must be such that condensation does not occur on any system part. Altitude and atmospheric pressure specifications are referenced to a standard day at 58.7°F (14.8°C). Maximum wet bulb temperature is 82°F (28°C).
Layout and space recommendations
Layout and space considerations are found in “System placement options” on page 56.
WARNING
Before the Symmetrix DMX-4 bays are rolled into position in the computer room, note how close the wheels are to the edge of the cutout. If the Symmetrix system needs to be relocated, contact the EMC Customer Support Center. For access floor-tile load requirements, refer to Table 13 on page 49.
CAUTION!When moving the storage bay down an incline, the rear of the cabinet must go first.
When moving the storage bay up an incline, the rear of the bay goes last.
Note: If a raised floor environment is used, 12 inches (30 cm) to 24 in. (60 cm) raised floor clearance for power cables and host cabling is recommended.
System host cabling requirements
The Presite Survey completed with the EMC Systems Engineer reports the cable lengths (Fibre Channel or serial) required for each host connection to the Symmetrix system. From a physical planning perspective, review the routing path(s) from the host(s) to the Symmetrix DMX-4 system. Resolve any physical access issues before the installation day.
Note: If host cables are run from overhead, a top cable management bracket, Model number DMX3-CBL BRKT, must be used.
Symmetrix DMX-4 system presite considerations 29

Physical Planning
Remote support Communication between the EMC Customer Support Center and the Symmetrix DMX-4 system occurs through EMC Secure Remote Support (ESRS). Connectivity is available using:
◆ A dedicated server (EMC recommended) that becomes the conduit for all communications between EMC and the site information structure. EMC provides Secure Remote Support Gateway software, at no-charge, to any customer with a maintenance agreement. Policy Manager software, also provided, allows customers to manage, control and log gateway actions.
The Gateway server can be placed in any customer-approved location as long as it can communicate with EMC over the Secure Socket Layer (SSL) and with the Policy Manager. The Gateway servers can be located on a:
• “Neutral zone” between the customer’s private network and the outside public network
• Dedicated VLAN
• Internal LAN
• The Policy Manager must be located on the internal LAN.
Refer to the following document located on EMC Powerlink®: EMC Secure Remote Support Gateway Site Planning Guide.
◆ An optional modem, available from EMC, that uses a regular telephone line or operates with a PBX.

Additional installation considerationsThe following options can be considered for current and future upgrade planning. Contact your EMC Sales representative for more information.
DMX-4 system securing kit
Some customers require that their EMC equipment be installed to withstand significant shock and vibration. Installation of EMC Symmetrix DMX-4 systems securing kits in combination with adequate substrate construction, will mitigate collateral damage during such events.
DMX-4 Silencer The Symmetrix DMX-4 Silencer is a fan noise reduction option for the Symmetrix DMX-4 system bay and storage bays. The Symmetrix DMX-4 Silencer is designed with leading edge sound reducing materials that attenuate high-frequency noise components and reduce overall sound levels. It is designed not to affect airflow or thermal performance.
Separated storage bay option
For some customers, physically separating two Symmetrix DMX-4 storage bays provides storage bay placement flexibility and addresses floor loading limitations within a data center. This capability and requirements are explained in “Separated storage bay planning” on page 61.
Planning for upgrades
When planning for upgrades, consider space, power, and environmental concerns.

Table 15 on page 50 provides the environmental requirements for shipping and storing a Symmetrix DMX-4.
Environmental acclimation
The DMX-4 system requires a period of time to become acclimated to a data center environment. Use the following process to prepare the system for the data center:
1. Completely remove all packing material from the system. Packaged accessory (i.e. Open First) boxes may remain with the system.
2. Dispose of the packing materials appropriately.
3. Move the system into its operating environment and allow the system to stabilize in the new environment for up to 16 hours as listed in Table 16 on page 51. If the operating system environments temperature and humidity are unknown then allow the system to stabilize in the new environment for 16 hours.

Air quality requirements
EMC Products are designed to be consistent with the requirements of the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE) Environmental Standard Handbook and the most current revision of Thermal Guidelines for Data Processing Environments, Second Edition, ASHRAE 2009b.
The Symmetrix DMX Series systems are best suited for Class 1 Datacom environments, which consist of tightly controlled environmental parameters, including temperature, dew point, relative humidity and air quality. These facilities house mission critical equipment and are typically fault tolerant, including the air conditioners.
The data center should maintain a cleanliness level as identified in ISO 14664-1, class 8 for particulate dust and pollution control. The air entering the Data Center should be filtered with a MERV 11 filter or better. The air within the Data Center should be continuously filtered with a MERV 8 or better filtration system. In addition, efforts should be maintained to prevent conductive particles, such as zinc whiskers, from entering the facility.
The allowable relative humidity level is 20-80% non condensing, however, the recommended operating environment range is 40-55%. For Data Centers with gaseous contamination, such as high sulfur content, lower temperatures and humidity are recommended to minimize the risk of hardware corrosion and degradation. In general, the humidity fluctuations within the Data Center should be minimized. It is also recommended that the Data Center be positively pressured and have air curtains on entry ways to prevent outside air contaminants and humidity from entering the facility.
For facilities below 40% relative humidity (RH), it is recommended to use grounding straps when contacting the equipment to avoid the risk of Electrostatic discharge (ESD), which can harm electronic equipment.
As part of an ongoing monitoring process for the corrosiveness of the environment, it is recommended to place copper and silver coupons (per ISA 71.04-1985, Section 6.1 Reactivity), in airstreams representative of those in the data center. The monthly reactivity rate of the coupons should be less than 300 Angstroms. When monitored reactivity rate is exceeded, the coupon should be analyzed for material species and a corrective mitigation process put in place.

EMC Symmetrix DMX-4 Physical Planning Guide
System placement optionsThe Symmetrix DMX-4 system configurations can be installed in several different flooring environments. The system can be installed on a solid floor or raised floor environment. Although it is not required, the raised floor environment is the preferred installation environment. “Floor load-bearing requirements” on page 56 describes the floor loading requirements for the Symmetrix DMX-4 installation. When planning the DMX-4 system placement, EMC recommends positioning the storage bay frame first so that the closed front door aligns with the floor tile edge. The system bay frame is then aligned with the storage bay frames and are bolted together later. When the system bay and all the storage bay doors are closed, the system bay is slightly recessed in relation to the storage bays because the depth of the system bay door is less than the depth of the storage bay doors. Figure 4 on page 59 shows the placement of a DMX-4 configuration with four storage bays on a level nonraised floor.
Note: In a nonraised floor environment, ensure the room meets environmental specification requirements. Refer to Chapter 3, ”Physical and Environmental Specifications,”.
Floor load-bearing requirements
It is recommended but not required that the Symmetrix DMX-4 configuration be installed on a raised floor. If the system is installed in a raised or nonraised floor environment, customer must ensure that the subfloor or site floor, respectively, is capable of supporting the system weight specified in Table 13 on page 49.
If the system is installed in a raised floor environment, customer must ensure that the raised floor is capable of supporting the system weight. EMC recommends the use of 24 X 24 inch heavy-duty, concrete-filled steel floor tiles. If different size or type of tile is used, customer must ensure that the tiles have a minimum load rating that is sufficient for supporting the system weight. To ensure proper physical support of the system, the following requirements, which are based on the use of 24 x 24 in. (61 x 61 cm) heavy-duty, concrete-filled steel floor tiles, must be complied with:
◆ Floor must be level.
◆ Floor tiles and stringers must be rated for a minimum static load of 1,600 lbs (725.7 kg) based on two casters of 800 lbs (362.9 kg) each per tile.
System Placement
◆ Floor tiles must be rated for a minimum of 1,000 lb (453.6 kg) rolling load.
◆ Floor tiles and stringers must be rated for a minimum static ultimate load of at least 3,000 lbs (1,360.8 kg) per tile.
◆ Floor tile deflection must be minimized with additional pedestal mounts.
◆ Do not position the system bay or storage bays with more than two casters on a single floor tile.
Note: Cutting tiles per specifications as shown on Figure 4 on page 59 will ensure the proper caster placement.
◆ Use or create no more than one floor tile cutout that is no more than 8 in. (20.3 cm) wide by 6 in. (15.3) deep in each 24 x 24 in. (61 x 61 cm) floor tile.
◆ Floor tile cutouts will weaken the tile. Therefore, at least one additional pedestal mount adjacent to the cutout of a tile is recommended. The number and placement of additional pedestal mounts relative to a cutout should be in accordance with the tile manufacturer’s recommendations.
◆ Care should be taken when positioning the bays to make sure that a caster is not moved into a cutout.
◆ Ensure that the weight of any other objects in the data center does not compromise the structural integrity of the raised floor and/or the subfloor (nonraised floor) of the data center.
WARNING
Customer must be aware that the load-bearing capacity of the data center floor is not readily ascertainable through a visual inspection of the floor and that the only definitive way to ensure that the floor is capable of supporting the load associated with the Symmetrix DMX-4 storage system is to have a certified architect or the data center design consultant inspect the specifications of the floor to ensure that the floor is capable of supporting the system weight specified in Table 13 on page 49. Customer is ultimately responsible for ensuring that the floor of the data center on which the Symmetrix DMX-4 system is to be configured is capable of supporting the system weight, whether the system is configured directly on the data center floor, or the system is configured on a raised floor supported by the data center floor.
System placement options 57
58
System Placement
Failure to comply with these floor-loading requirements could result in severe damage to the Symmetrix DMX-4 system, the raised floor, subfloor, site floor and the surrounding infrastructure should the raised floor, subfloor and/or site floor fail.
NOTWITHSTANDING ANYTHING TO THE CONTRARY IN ANY AGREEMENT BETWEEN EMC AND CUSTOMER, EMC FULLY DISCLAIMS ANY AND ALL LIABILITY FOR ANY DAMAGE OR INJURY RESULTING FROM CUSTOMER’S FAILURE TO ENSURE THAT THE RAISED FLOOR, SUBFLOOR AND/OR SITE FLOOR ARE CAPABLE OF SUPPORTING THE SYSTEM WEIGHT AS SPECIFIED ABOVE. CUSTOMER ASSUMES ALL RISK AND LIABILITY ASSOCIATED WITH SUCH FAILURE.
Overhead host cable routing
When installing a DMX-4 system on a nonraised floor (or in some instances on a raised floor), the host cabling is handled from the overhead. To assist in the management of overhead host cable routing, a topside cable routing bracket, (Model # DMX3-CBL BRKT) must be purchased and installed at the rear of the equipment bay.
Overhead power cable routing
If the customer requires power to be supplied from overhead, then EMC recommends the power cables be "dropped" on the outside of the cabinet next to the hinge side of the doors and routed inside the machine. The cable retainer bracket will be removed to allow the cables inside the machine and replaced after cable routing is complete. The cables should be dressed to allow all doors to open freely. The customer is responsible for meeting all of his/her local installation safety requirements.
Symmetrix DMX-4 system floor tile cut-outs
The DMX-4 system can be configured with one system bay and various increments of one to eight storage bays. Figure 4 on page 59 illustrates the configuration and the recommended floor tile cutout placement for the largest system available. To plan for a smaller system, remove storage bays around the system bay as necessary.

EMC Symmetrix DMX-4 Physical Planning Guide
System Placement
Separated storage bay planning
For some customers, physically separating two Symmetrix storage bays provides storage bay placement flexibility and addresses floor loading limitations within a data center. Multiple separated storage bays are allowed on each side of the system bay. This section provides an overview for the planning requirements needed to install a DMX-4 system separating two or more daisy-chain storage bays from an adjacent storage bay.
IMPORTANT!Each Symmetrix storage bay separation configuration requires authorization by EMC using EMC’s RPQ process to determine the feasibility and requirements for the customer’s data center.
Separated storage bay configurations
When planning for a Symmetrix DMX-4 separated storage bay configuration consider the following:
◆ Enginuity revision 5772.88.80 or later is required for a separated storage bay configuration.
◆ Any storage bay that is not directly connected to the system bay can be installed separated from another storage bay for a new system or as an upgrade.
Note: The two storage bays that connect directly to the system bay cannot be separated from the system bay.
◆ A separated storage bay is not physically bolted to the bay to which it will be cabled.
◆ A separated storage bay can be located up to approximately 12 feet (3.65 meters) as shown in Figure 9 on page 64. Actual separation distance will be determined on a case by case basis and will depend on the customer’s configuration, cable routing and data center design.
◆ A separated storage bay is cabled to the adjacent storage bay (32 cables—2 bundles of 16 cables).
◆ Separated storage bays should be located on one side (left or right) of the system bay. Viewing from the front, the following bays can be configured as separated storage bays:
• Bays 2A, 3A and 4A - left of the system bay
• Bays 2B, 3B, and 4B - right of the system bay
System placement options 61

System Placement
Separated storagebays in a raised floor
environment
In a raised floor environment, the separated storage bay cables can be routed under the floor using any of the following:
◆ An EMC supplied GridRunner
◆ Acustomer-supplied cable trough
◆ Both the GridRunner and the customer-supplied cable trough
The GridRunner and cable trough support the two cable bundles and protects them when used in a raised floor environment. The maximum distance between the separated storage bay and the adjacent bay when using a GridRunner or a cable trough is illustrated in Figure 7 on page 62.
Figure 7 Separated storage bay with cable trough (rear view)
Note: A+2C in Figure 7 on page 62 is less than or equal to 365.8 cm (144 in).
Separated storagebays in a nonraised
floor environment
In a nonraised floor environment, the separated storage bay can be installed using an overhead method that uses an EMC-supplied modified Symmetrix top cover and a customer-supplied overhead cable trough. The maximum distance between the separated storage bay and the adjacent bay a with a customer-supplied overhead cable trough is illustrated in Figure 8 on page 63.

DMX-4 dedicated power requirements
Before the DMX-4 system is delivered, the customer must supply and install the required receptacles on two separate power distribution units (PDUs) for zone A and zone B power for the Symmetrix DMX-4 system bay and each storage bay. DMX-4 power redundancy can only be assured at the customer PDU and after. Figure 11 on page 67, represents the label attached to each power cable exiting the Symmetrix DMX-4 system bay and each storage bay. These labels are only to be removed from the cables by the customer’s site electrician.

EMC Symmetrix DMX-4 Physical Planning Guide
Power Requirements
Symmetrix touch current compliance
CAUTION!The Symmetrix DMX-4 cabinet power supplies should not be connected on the separate Main and Auxiliary circuit panels to differential trip devices. These devices are typically called GFCI (Ground Fault Circuit Interrupter), GFI (Ground Fault Interrupter), ELCB (Earth Leakage Circuit Breaker), or Residual Current Circuit Breakers.
The Symmetrix DMX-4 system is designated as fixed (stationary) electrical equipment with high earth-leakage markings. The intention is to connect the cabinets to the customer AC supply with the recommended rated current breakers (refer to “Electrical specifications and power requirements” on page 72 for recommended circuit breaker ratings) and the attached cables. These recommended breaker ratings are based on the maximum kW loading of the cabinet and not on the KVA figures of a particular configuration. The KVA values listed in this manual (refer to “Power and cooling data” on page 54) are intended for air conditioning and utility loading purposes only.
Because the Symmetrix DMX-4 system is a high earth-leakage device, differential trip devices (typically 30 mA) are not recommended due to random activations during utility feed distortions and powerline transients interacting with the cabinet noise filters.
These differential devices can be called GFCIs, GFIs, ELCB, or other names, but typically have trip ratings of 5 mA to 500 mA and are mostly intended for consumer goods rather than fixed devices.
If the Symmetrix cabinet is correctly grounded to the customer’s AC power source, leakage current should not produce a voltage leading to electrical shock. Serious insulation breakdowns should trip the breakers feeding the cabinet or, preferably, should first clear fuses in individual internal modules closest to the fault.
Symmetrix DMX-4 power overview 69

Power Requirements
Regulatory compliance
The Symmetrix DMX-4 system meets regulatory requirements as referenced by the following UL/IEC/EN 60950 3d Edition:
5.1.7 Equipment with touch (leakage) current exceeding 3.5mA
For Stationary Permanently Connected Equipment, or Stationary Pluggable Equipment Type B, having a main protective earthing terminal, if the Touch (Leakage) Current measurements exceed 3.5mA r.m.s., following conditions apply:
• The r.m.s. Protective Conductor Current will not exceed five percent of the input current per line under normal operating conditions. If the load is unbalanced, the largest of the three-line (phase) currents shall be used for this calculation.
To measure the Protective Conductor Current, the procedure for measuring Touch Current is used, but the measuring instrument is replaced by an ammeter of negligible impedance.
• The cross-sectional area of the Protective Bonding Conductor will not be less than 1.0 mm squared in the path of high Protective Conductor Current.
• A label with similar wording shall be affixed adjacent to the equipment AC MAINS SUPPLY connection:
HIGH LEAKAGE CURRENTEarth connection essential before connecting supply.
The Symmetrix DMX-4 configurations are Stationary Pluggable Type B systems, and have been extensively tested and certified to meet the above standard, including the application of the warning label, EMC P/N 046-000-309, in English and French. The label location for the Symmetrix DMX-4 configuration is on the inside of the front door.
EMC Symmetrix DMX-4 Physical Planning Guide
Power Requirements
Choosing a UPS The Symmetrix DMX-4 system is capable of supporting two consecutive five minute power outages before its battery backup unit is depleted. To extend this time period, purchase a UPS from a qualified vendor.
EMC neither offers nor recommends any specific UPS suppliers or product type for its customers. However, EMC uses preferred suppliers for UPS systems in their facilities. Therefore, if you, the customer, are implementing a UPS, EMC recommends the following:
◆ When you are planning the UPS solution for the Symmetrix system and the host system is presently (or will potentially be) protected with a UPS, the battery backup time you propose for the Symmetrix UPS solution should match that of the host system.
◆ The Symmetrix system requires independent Zone B and Zone A power feeds for each bay.
◆ The UPS should be equipped with an internal output isolation transformer.
◆ The UPS should be installed as a separately derived AC source using neutral and ground wiring to preserve the (2N) fault tolerance specification of the Symmetrix power system.
◆ Depending on the power requirements for your Symmetrix system operation, an isolation transformer/stabilizer installed in front of the UPS could further buffer the AC utility environmental factors from reaching the Symmetrix system. To determine if an isolation transformer/stabilizer is needed, consult a licensed electrician.

Electrical specifications and power requirementsThis section describes electrical specifications, power cables, connectors, and extension cords for the Symmetrix DMX-4 system bay and storage bays for North American and international sites.
System and storage bays that support three-phase power include two power zones with two PDPs in each zone. Earlier versions of extension cords that connect to customer power are black. Later versions are color-coded in black and gray and connect as follows:
◆ Black extension cables connect to the PDP in zone B.
◆ Gray extension cables connect to the PDP in zone A.
North American power specifications
Table 20 on page 72 describes the North American electrical specifications for the Symmetrix DMX-4 system. Specifications are for a single system bay or storage bay.
North American extension cords and mating connectors
Each DMX-4 system bay and storage bay has two PDPs with a power cable affixed to each PDP (Figure 10 on page 66). For a North American, three-phase Delta configuration, affixed to each PDP power cable is a 50A Hubbell CS8365C or an equivalent 8365 type connector.
