Installing the optional wall mountInstalling the C1G hardware 2-7

Installing the optional wall mountCasa provides a C1G wall mounting option for installations where a computer rack is not readily available or feasible, or if the installation space is limited. The C1G wall mounting components attach to any flat wall surface. Since the system is mounted flush (similar to hanging a picture on a wall) with approximately 0.30 inches of clearance between the unit and the wall, you only need to ensure adequate mounting points and a surface area large enough for the system and the system cabling.

There are currently two wall mounting options:

1. The standard wall mount kit, and

2. The standard wall mount with a remote standalone dual power module holder. See “Using the standalone dual power module pocket.”

Figures 2-4 illustrate the wall mount bracket installation.

The GigE ports labeled G0 and G1 require the insertion of an SFP module (SFP-CP copper or SFP-LC fiber), as illustrated in Figure 3-1. The following warning applies to fiber-optic SFPs.

Figure 3-1. Sample SFP module

To insert an SFP module into port GigE G0:

Warning: Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments.


Connecting the Gigabit Ethernet portsConnecting and starting the C1G 3-3

1. For optical SFP modules, locate the transmit (TX) and the receive (RX) markings that identify the topside of the SFP module.

2. Align the back (receive) end of the SFP module with the front faceplate, then insert the module into the G0 port until you feel the connector snap into place.

3. Remove the dust plugs from the optical ports, and store them for later use.

Connecting Ethernet to the SFP

To connect Ethernet cables to the SFPs in ports G0 and G1, insert the Ethernet cable into the front (transmit) end of the SFP module, as illustrated in Figure 3-2.

Figure 3-2. Connecting Gigabit Ethernet ports

Note: On some modules, the TX and RX markings might be replaced by arrowheads. These point out of the module connector to signify the transmit direction, and into the connector to indicate the receive direction.

Removing Ethernet cables and the SFP module

To remove an SFP module:

1. Remove the cable from the front end of the SFP module in G0 or G1. To release the lock on the SFP, pull the SFP module release lever down until it stops.

2. Slide the module out of the receptacle.

Replace the dust plugs on the optical ports for protection.

Connecting to the console port

The console port provides local administrative access to the C1G and the command-line interface (CLI) over a serial EIA-561 RS232D connection with a DTE interface using a male RJ-45 plug. Attaching a terminal or PC allows you to connect to the system CLI for initial setup at the deployed location.

To connect a terminal or PC to the RJ-45 console port, you need a DB-9 to DB-9 serial crossover cable and the supplied RJ-45 to DB-9 adapter.

Figure 3-3 illustrates the RJ-45 and lists the pin/signal information.


Connecting to the console portConnecting and starting the C1G 3-5

Figure 3-3. .RS-232 pinouts on console port

A console connection kit is shipped with each C1G system. The kit includes the following components:

• One standard Category 5 UTP RJ-45-to-RJ-45 cable

• One RJ-45 to DB-9 adapter

• One DB9-to-DB9 serial crossover console cable (also called a null modem cable)

Use these components to connect the console port to a terminal or PC, as illustrated in Figure 3-4.

1. Connect one end of the RJ-45 cable to the serial RJ-45 port.

2. Connect the other end of the cable to the RJ-45-to-DB-9 adapter.

3. Connect the adapter to the appropriate serial port on the PC or terminal to complete the console port cable connection.

4. Power on the PC or terminal.

5. Configure the PC terminal emulation software or the terminal for the following default settings:

• 115200 baud

Connecting the RF I/O portsConnecting and starting the C1G 3-7

Connecting the RF I/O ports Connect the RF I/O upstream and downstream ports to the HFC network, as illustrated in Figure 3-5:

1. Attach the 75-ohm F-connector on one end of the cable to the RF connector on the faceplate of RF I/O module.

2. Attach the other end of the cable to the equipment that acts as a gateway to the HFC network, using the appropriate type of connector for your HFC distribution equipment.

Figure 3-5. Connecting the upstream and downstream ports.

Caution: When connecting the cable F-connector to the RF connector on the RF I/O module, ALWAYS use a torque wrench to set the tightness to 15 inch-lbs (1.7 Newton-meters) Do not simply hand-tighten the F-connectors. F-connectors that are too loose can cause RF leakage. F-connectors that are too tight can damage the RF port electronics.

Secure RG6 F-connectorsto upstream and downstreamports. Tighten to 15 inch-lbs of torque.

Connecting the DC power modulesHardware Installation Guide3-8

Connecting the DC power modulesLocate the two DC power modules included with the C1G. The modules provide redundant 12V DC power to the system by converting the each 120VAC voltage source. The DC power modules are designed to fit and drop into the dual power module support attached to the left side of the system, as covered in Chapter 2, “Installing the C1G hardware.”

Perform the following steps:

1. Without the power cords installed, insert and place the two DC power modules into the power supply bays and at the same time, route the cables that go to the A and B power inputs through the hole provided in the rack-mount sheet metal

2. Plug-in the A and B inputs to the C1G.

3. At the back of the system, plug in the two AC power cords.

4. When ready, plug in the power cords into the AC power outlets.

Figure 3-6 shows the redundant power module hookups.
