Chapter 2 Installing Cisco Network Modules in Cisco Access Routers
Removing or Replacing Cisco Network Modules for Cisco Access Routers
Caution
Online removal of disks without proper shutdown can result in file system corruption and might render
the disk unusable. The operating system on the applications or services network module must be shut
down in an orderly fashion before the network module can be removed.
To perform online removal of a Cisco application and service network module and insertion of a
replacement, follow these steps with the router in privileged EXEC mode:
Step 1
Initiate an application and service network module console session using the following command:
Router#
service-module service-engine
slot/port
session
Trying 10.10.10.1, 2129 ... Open
SE-netmodule>
enable
Password:
SE-netmodule#
SE-netmodule con now available
Press RETURN to get started!
SE-netmodule>
enable
Password:
SE-netmodule#
Timesaver
Cisco application and service network modules use a blank password. Press
Enter
at the password
prompt.
Step 2
Save the running configuration for the network module by entering the following command from the
SE-netmodule
prompt:
SE-netmodule#
copy running-config ftp:
Address or name or remote host?
username
/
password
/
remote host
Destination filename?
filename
Step 3
Exit the network module console session by pressing
Ctrl-Shift-6
, followed by
x
.
Step 4
On the router, clear the network module console session with the following command:
Router#
service-module service-engine
slot
/
port
session clear
Step 5
Perform a graceful halt of the network module disk drive with the following command:
Router#
service-module service-engine
slot
/
port
shutdown
Step 6
Remove the network module, using the procedure described in the
“Removing or Replacing
Single-Wide, Extended Single-Wide, and Extension Voice Network Modules from Cisco Access
Routers” section on page 2-19
.
Step 7
Install the replacement network module, using the procedure described in the
“Installing Cisco Network
Modules in Cisco Access Routers” section on page 2-5
.
Step 8
Check that the network module LEDs come on and that the Active/Ready LEDs on the router front panel
also come on. This inspection ensures that connections are secure and that the new unit is operational.
