Chapter 45 Troubleshooting

Recovering from a Lost or Forgotten Password

Follow the steps in this procedure if you have forgotten or lost the switch password.

Step 1 Use one of these methods to connect a terminal or PC to the switch:

•Connect a terminal or a PC with terminal-emulation software to the switch console port. If you are recovering the password for a switch stack, connect to the console port of the stack master.

•Connect a PC to the Ethernet management port. If you are recovering the password for a switch stack, connect to the Ethernet management port of a Catalyst 3750-E stack member. For details about using the Ethernet management port, see the “Ethernet Management Port” section on page 11-12and the hardware installation guide.

Step 2 Set the line speed on the emulation software to 9600 baud.

Step 3 On a Catalyst 3750-E switch, power off the standalone switch or the entire switch stack. On a Catalyst 3560-E switch, power off the switch.

Step 4 Reconnect the power cord to the Catalyst 3560-E switch, the Catalyst 3750-E standalone switch, or the stack master. Within 15 seconds, press the Mode button while the System LED is still flashing green. Continue pressing the Mode button until the System LED turns briefly amber and then solid green; then release the Mode button.

Several lines of information about the software appear with instructions, informing you if the password recovery procedure has been disabled or not.

•If you see a message that begins with this:

The system has been interrupted prior to initializing the flash file system. The following commands will initialize the flash file system

proceed to the “Procedure with Password Recovery Enabled” section on page 45-5, and follow the steps.

•If you see a message that begins with this:

The password-recovery mechanism has been triggered, but is currently disabled.

proceed to the “Procedure with Password Recovery Disabled” section on page 45-7, and follow the steps.

Step 5 After recovering the password, reload the Catalyst 3560-E switch or the Catalyst 3750-E standalone switch or the stack master.

On a Catalyst 3560-E switch:

Switch> reload

Proceed with reload? [confirm] y

On a Catalyst 3750-E switch:

Switch> reload

slot <stack-master-member-number>

Proceed with reload? [confirm] y

Step 6 For Catalyst 3750-E switches, power on the rest of the switch stack.
