Recovering from a Failed Command Switch Without HSRP
If a command switch fails and there is no standby command switch configured,
member switches continue forwarding among themselves, and they can still be
managed through normal standalone means. You can configure member switches
through the console-port CLI, and they can be managed through SNMP, HTML,
and Telnet after you assign an IP address to them.
The password you enter when you log in to the command switch gives you access
to member switches. If the command switch fails and there is no standby
command switch, you can use the command-switch password to recover. For more
information, see the “Recovering from a Command Switch Failure” section on
page 9-14.
Recovering from a Lost or Forgotten Password
Follow the steps in this procedure if you have forgotten or lost the switch
password.
Step 1 Connect a terminal or PC with terminal emulation software to the console port.
For more information, refer to the switch installation guide.
Note You can configure your switch for Telnet by following the procedure
in the “Accessing the CLI” section on page 3-8.
Step 2 Set the line speed on the emulation software to 9600 baud.
Step 3 Unplug the switch power cord.
Step 4 Press the Mode button, and at the same time, reconnect the power cord to the
switch.
You can release the Mode button a second or two after the LED above port 1X
goes off. Several lines of information about the software appear, as do
instructions:
The system has been interrupted prior to initializing the flash file
system. The following commands will initialize the flash file system,
and finish loading the operating system software:
