Chapter 2 Installing the Cisco IPVC 3500 Series Gateway
Installing the Cisco IPVC 3540 PRI Gateway
Caution
Cisco IPVC 3540 modules contain ESD-sensitive components. Use proper ESD procedures when
handling the modules. Improper handling can damage the module and cause the module to fail
immediately or at a later time.
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Warning 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.
Warning 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.
Warning
The telecommunications lines must be disconnected 1) before unplugging the main power connector
and/or 2) while the housing is open.
Installing the PRI RTM in the Cisco IPVC 3544 Chassis Top Slot
The top slot in the Cisco IPVC 3544 chassis is used to provide system functionality to the cPCI bus. This
functionality is embedded in the gateway module which connects to the bus through the RTM. This
section describes how to install the RTM in the chassis top slot to allow the gateway module to
communicate with the cPCI bus.
Procedure:
Step 1
Disconnect the power cable to the chassis to ensure that the power is turned off.
Step 2 On the back of the chassis, loosen the screws that secure the latches of the top cover panel.
Step 3
Press the red release button and snap the black handles back to open the latches.
Step 4 Slide the RTM out two inches to expose the cable.
Step 5
Remove the 16-pin flat cable attached to the board.
We recommend that you place the blade of a small, flat-blade screwdriver at the base of the cable
connector key, and pry the connector upward to remove the cable.
Caution
Damaging the cable results in the LEDs on the chassis not working.
Step 6
Remove the RTM from the chassis.
Step 7 Remove the PRI RTM from the antistatic bag.
Step 8
Align the edges of the PRI RTM with the chassis guide rails.
