Safety Recommendations Follow these guidelines when working on equipment powered by electricity: • Locate the emergency power-OFF switch in the room in which you are working. Then, if an electrical accident occurs, you can quickly shut the power OFF. • Before working on the router, turn OFF the power and unplug the power cord.
For safety, periodically check the resistance value of the antistatic strap, which should be Caution between 1 and 10 megohms (Mohm). Required Tools and Equipment You need the following tools and equipment to install a WAN interface card in a Cisco 3600 series router: • WAN interface card •...
Installing a BRI WAN Interface Card in a Router Figure 3 Termination Jumpers on the BRI S/T WAN Interface Card No termination 100 Ohms termination Termination jumpers Installing a BRI WAN Interface Card in a Router WAN interface cards do not support online insertion and removal (hot swap). Before Caution inserting a WAN interface card into a 2-slot network module that is already installed in the router chassis, you must turn OFF electrical power and disconnect network cables.

Configuration Mode You can configure the BRI interface on your BRI WAN interface card manually, by entering Cisco IOS commands on the command line. This method, called configuration mode, provides the greatest power and flexibility. Before you begin, disconnect all WAN cables from the router to keep it from trying to run the AutoInstall process.

Configuring the BRI Interface AutoInstall The AutoInstall process is designed to configure the router automatically after it connects to your WAN. For AutoInstall to work properly, a TCP/IP host on your network must be configured to provide the configuration files. The TCP/IP host can reside anywhere on the network if the following two conditions are met: •...
