Prerequisites for Installing the Cisco WAE Network Modules

The prerequisites for installing the Cisco WAE network module in the access router are as follows:

•Plan software upgrades or downgrades for times when you can take all applications that run on the host router offline.

•Ensure that you have the appropriate Cisco access router to serve as the host router. The WAE network module is supported on the following Cisco access routers:

–2811, 2821, and 2851

–3725, 3825, and 3845

•Ensure that the router is running IOS Release 12.4(9)T or 12.4(9)T1 (recommended) by using the show version command.

When minimum release requirements are met, you can change images on either the router or the network modules without affecting performance.

•For information about installing the NME-WAE, see the Quick Start Guide: Network Modules for Cisco Access Routers and Cisco Network Modules and Interface Cards Regulatory Compliance and Safety Information.

•You need the slot and unit numbers for the “Setting Up Network Module Interfaces” section on page 6 and the “Opening and Closing a Network Module Session” section on page 8. Make a note of the network module location in the host router:

–slot—Slot number of the network module in the router chassis. After you install the module, you can obtain this information from the router show running-configcommand output.

–unit—Number of the daughter card on the module. This value is always 0.

•You need an accessible FTP or TFTP file server.

–Use an FTP file server for installations, backups, and restores.

–Use a TFTP file server (on the FTP-file-server machine) for boothelper operations to recover from a failed installation.
