Setting the boot PROM password for a Backbone without a recovery
string
This procedure applies to the Brocade DCX, DCX-4S, DCX 8510-4, and DCX 8510-8 Backbones.
On the Brocade DCX Backbone, 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 over a serial or Telnet connection 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 Connecting to Fabric OS through
the serial port on page 38.
4. 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.
