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-config command 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.
Restrictions for Cisco WAE Network Modules
The restrictions for the Cisco WAE network modules are as follows:
• You may perform a software upgrade or downgrade only on an inactive appliance. Plan upgrades or
downgrades for times when you can take all applications that run on the host router out of service
or offline.
• All WAE appliances and network modules that are in your network must be running the same version
of the ACNS software.
• Network module software configurations can only be performed by using a console that connects to
a single serial-port console port on the host router.
