Chapter 2 Installing the Cisco Unified Videoconferencing 3545 Gateway
Installing the Gateway
Installing the Gateway
This section describes how to insert a gateway into the Cisco Unified Videoconferencing 3545 chassis.
Before You Begin
Note the following:
• The Cisco Unified Videoconferencing 3545 chassis has four slots. You can install the Cisco Unified
Videoconferencing 3545 Gateway in any of the slots.
• Insert the gateway in the top slot at the front of the Cisco Unified Videoconferencing 3545 chassis
to view status and identification information via the System web user interface.
The Cisco Unified Videoconferencing 3545 Gateway has two components that you must install in the
chassis: the Cisco Unified Videoconferencing 3545 Gateway module and the corresponding Rear
Transition Module (RTM), as indicated in Table 2-5.
The gateway module installs in the front of the chassis and provides ISDN or serial functionality. The
RTM installs in the rear of the chassis and provides the physical interface for the ISDN or serial line.
You must install these modules in corresponding slots in the chassis. That is, if you insert the gateway
module in the top slot in the front of the chassis, you must insert the RTM in the top slot in the rear of
the chassis.
Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the
backplane with your hand or any metal tool, or you could shock yourself.
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
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.
