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 56.
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.
5. Press Esc within four seconds after the message
Press escape within 4 seconds... is
displayed.
