Installing the Gateway
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.
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 ).

Step 7 Use even pressure to push the module further into the slot.
Caution Do not force the connection. Forcing the connection can bend or damage the pins in the
connector inside the chassis.
Step 8 Snap the handles forward to secure the RTM module in the slot.
Step 9 Secure the RTM module screws.
