The following options are available:

4. Enter 3.

5. At the shell prompt, enter the passwd command.

SilkWorm 12000, 24000, and 48000

On the SilkWorm 12000, 24000, and 48000, set the password on the standby CP blade, fail over, and

then set the password on the previously active (now standby) CP blade to minimize disruption to

the fabric:

1. Determine the active CP blade by opening a telnet session to either CP blade, connecting as admin,

and entering the haShow command.

2. Connect to the active CP blade by serial or telnet and enter the haDisable command to prevent

failover during the remaining steps.

3. Create a serial connection to the standby CP blade as described in “To connect through the serial

port” on page 2-2.

4. SilkWorm 12000: Reboot the standby CP blade by pressing the yellow ejector buttons at top and

bottom of the CP blade, then pressing both ejector handles back towards the switch to lock the

blade back into the slot.

SilkWorm 24000 and 48000: Reboot the standby CP blade by sliding the On/Off switch on the

ejector handle of the standby CP blade to Off, and then back to On.

This causes the blade to reset.

5. Press ESC within four seconds after the message “Press escape within 4 seconds...” displays.
