I was trying to access Catalyst Blade Switch 3020 through serial port to reset the lost password. This Switch is plug-in to HP c7000 Chassis. I followed the instruction from Cisco documentation for this password re-set process as follows.
{ Step 1 Connect a terminal or PC with terminal-emulation software to the switch console port.
Step 2 Set the line speed on the emulation software to 9600 baud.
Step 3 Push the release latch on the front of the switch to the open position.
Step 4 Pull the switch partially out of the module bay until the power disconnects, and then push it in again. The switch restarts when it reseats in the server chassis. The switch performs POST after power is applied.
Step 5 Push the release latch on the front of the switch to the closed position.
Step 6 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.
------- Step 6 did not work. System LED neither flashing nor in Solid state. I can not connect through Serial port any more! Any help.....
