Chapter 6 Installation and Preparation

6.1 Preparation and checkup before installation

Ready this manual carefully, ensure the power supply is in range or operating condition, the rack has been well connected with earth. Preparing the necessary cables and make sure there is no short circuit or open circuit.

Check whether the type of device, spare parts and number are same with that of packing list. Make sure the device appearance is in excellent condition. There must be drying process if the device has been damp.

6.1.1 Matching the E1 cable with device type Use 75 ohm unbalanced BNC cable prepared by users for E1 cable.

6.1.2 Ethernet cable and connection requirement Use CAT-5 twisted pair to connect OPCOM3105-155, be noted the length of twisted pair should not exceed 100 meters. It is recommended to use 0.6mm (22AWG) twisted pair when connect with RJ-45 interface.

Auto-MDI/MDIX function is enabled when electrical interface Auto-Negotiation enables, straight or crossover cables can be adopted to connect with other devices in this case.

6.1.3 Matching the fiber medium with OPCOM3105-155 OPCOM3105-155-S1/S2/S3 adopts single-mode fiber, the connector is DSC.


13

OPCOM3105-155-SS1/SS2 devices are of single-mode single-strand dual-wavelength interface, adopts single-mode fiber, the connector is SC/PC.

6.2 Installing procedures

6.2.1 Preparation for installation Fix the device into 19 inches rack or set it at a smooth and safe place.

6.2.2 Connecting the device The fiber connection methods are different in different topologies and in different protection patterns.

Note: Single-strand optical module should be used in pairs. EAST optical interface of single-mode optical interface transmitting wavelength is 1310nm, WEST optical interface transmitting wavelength is 1550nm. Thus, when two single-strand devices are connected, optical interface 1 of one of them should connect with optical interface 2 of the other one.

(1) Point-to-point topology

Point-to-point connection is the simplest application, no matter protected or not, the connection pattern doesn’t change, as Figure 6-1 shows:

6.2.3 Power on the device After power on OPCOM3105-155, PWR indicator will turn on. When SYS indicator on the front panel starts flashing, the device finishes initialization. If STM-1 optical interface and other SDH device optical interfaces are connected correctly, LOS and LOF indicators will turn off.

In Auto-Negotiation mode, ETH interface and SNMP interface are connect with other devices separately, LNK/ACT indicator on the panel will turn on, if there is data being transmitted or received, the indicator will flash.

Note: DC-48V power supply is recommended to connect with earth (the middle terminal of DC terminals). Pay much attention that the poles can not connect inversely, -48V terminal connects lower electricity, BGND terminal connects higher electricity.

Appendix B FAQ If you have problems during the installation or application, please try to solve them through the following suggestions. And if it does not work, please contact the sellers to get technical supports.

1. Q: PWR light of power supply card turns OFF.

A: Check the power supply cable first, and then the power supply card.

2. Q: LOS alarms of SDH optical interface.

A: That is to say, there is receiving signal loss. First, check whether the cable is connected correctly; second, if there are still alarms when self-loop the cable (perhaps optical attenuation is needed), change the cables; if there are still alarms then there is something wrong with device.

3. Q: Indicator light of SNMP network management interface is OFF.

A: First, check whether the cable works normally or not; then, check whether the devices connect to SNMP network management interface works normally or not. And make sure the cable is correct.

4. Q: E1 channel failed.

A: Check the E1 cable, optical interface and time slot configuration, check the alarms in the EMS and use loop back function to find where the problem is.
