Clearing the Switch Module IP Address and Configuration
Clearing the Switch Module IP Address and Configuration
This section describes how to reset the switch module by rerunning the initial configuration dialog
(system configuration dialog). These are reasons why you might want to reset the switch module:
• You installed the switch module in your network and cannot connect to it because you assigned the
wrong IP address.
• You want to clear all the configuration settings from the switch module and assign a new IP address.
Caution This procedure clears the IP address and all configuration information stored on the switch module. Do
not follow this procedure unless you want to completely reconfigure the switch module.
To reset the switch module:
1. At the switch module prompt, enter enable, and press Return or Enter.
2. At the Privileged EXEC prompt, switch module#, enter setup and press Return or Enter.
The switch module displays the prompt to run the initial configuration dialog. The switch module now
behaves like an unconfigured switch module. You can configure the switch module by using the CLI
setup procedure described in
Appendix C, “Configuring the Switch with the CLI-Based Setup Program”
Replacing a Failed Stack Member
If you need to replace a failed stack member, you can hot swap or replace the switch module by following
this procedure:
1. Get a replacement switch module that has the same model number as the failed switch module.
2. Power down the failed switch module through the Onboard Administrator.
3. Install the replacement switch module in the server chassis.
If you manually set the member numbers for any members in the stack, you need to manually assign
the replacement switch module with the same member number as the failed switch module.
To
manually assign the member number, install the replacement switch module, and wait for it to
boot up. Use the CLI to manually assign the member number (see the software configuration guide
for instructions) before you connect the switch module to the stack.
4. Connect the switch to the stack.
5. Make the same Gigabit Ethernet connections on the replacement switch module that were on the
failed switch module.
6. Reinstall any transceiver modules and cable connections.
7. Power on the replacement switch through the Onboard Administrator.
The replacement switch module will have the same configuration for all the interfaces as the failed
switch module and will function the same as the failed switch module.
