Installing a Network Module or Interface Card
This chapter describes how to install network modules in a Cisco 2600 Series router, and includes
information on installing either a WAN interface card or a voice interface card (VWIC) into the
appropriate network module. The chapter contains the following sections:
•
Installing a Network Module
•
Installing a WAN Interface Card
•
Installing a Voice Interface Card
Note
WAN and voice interface cards can be installed in the network module either before or after the
network module is installed in the router chassis.
Installing a Network Module
The following instructions apply only to installing a network module in a modular router chassis slot.
You can install network modules in the chassis either before or after mounting the router, whichever is
more convenient.
Warning
Before installing a network module into the router chassis, turn OFF electrical power to the router
to avoid the risk of electrical shock to yourself or to the equipment. To see translations of the
warnings that appear in this publication, refer to the
Regulatory Compliance and Safety
Information
document that accompanied this device.
Tip
Unless the router is using a copy of the Cisco IOS Release 11.3(3)T or later release, you cannot
install an ISDN BRI network module (or ISDN BRI WAN interface card) into the same chassis as an
ISDN PRI network module.
The following tools are required or recommended for this task:
•
ESD-preventive wrist strap
•
Number 1 Phillips screwdriver
•
Duct or electrical tape (for routers using a DC power supply only)
