Chapter 2 Installing the Cisco Unified Videoconferencing 3545 Gateway

How to Install the Gateway

Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord.

Before opening the chassis, disconnect the telephone network cables to avoid contact with telephone network voltages.

To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.

The telecommunications lines must be disconnected 1) before unplugging the main power connector and/or 2) while the housing is open.

Installing the RTM Module

This section describes how to install the RTM module in the Cisco Unified

Videoconferencing 3545 chassis. The Rear Transition Module (RTM) provides the ISDN or serial line connections for the gateway.

Before You Begin

Warning You must install the RTM module before you install the gateway module. Inserting an RTM module in the rear of the chassis when a gateway module is already installed in the same position at the front of the chassis may damage the chassis.

Procedure

Step 1 On the back of the chassis, loosen the screws of the blank panel covering the slot into which the RTM module is to be installed.

Step 2 Remove the blank panel.

Step 3 Remove the new RTM from the antistatic bag.

Step 4 Press the red buttons and open the handles of the RTM module.

Step 5 Align the edges of the RTM module with the chassis guide rails.

Step 6 Slide the RTM module into the chassis until it stops (see Figure 2-5).
