Brocade DCX 8510-4 Backbone Hardware Reference Manual 67
53-1002177-05
Control processor blade (CP8) removal and replacement
5
ATTENTION
Brocade’s firmware upgrade policy for CP8 blades specifies testing for the current Fabric OS release
and one version earlier. It is possible to upgrade by more than one version, but it is a very specific
and detailed process. Read the directions under “Downloading firmware from an FTP server” or
“Downloading firmware from a USB device” carefully.
ATTENTION
If the new CP blade does not have the same firmware as the active CP blade, the new blade must
be upgraded to the same firmware version. You can determine the firmware version on the
replacement blade and do a firmware upgrade if necessary after inserting the blade in the chassis,
but you MUST disable high availability (HA) before inserting the new blade. If the new CP blade is
severely down-level, a very specific procedure must be followed to bring the blade up to the correct
firmware version.
NOTE
For the DCX 8510-4, slots are numbered from 1-8 from bottom to top, viewed from the port side of
the chassis.

Time and items required
The replacement procedure for the CP blade takes approximately 30 minutes. The following items
are required for the CP blade replacement:
• ESD (electrostatic discharge) grounding strap.
• Workstation computer.
• Serial cable.
• IP address of an FTP server for backing up the Brocade DCX 8510-4 configuration.
• #2 Phillips screwdriver.
• Replacement Brocade DCX 8510-4 control processor blade (CP8).
• If you are upgrading through multiple versions of the Fabric OS, consult the “Steps for
upgrading through multiple versions of Fabric OS” table to see which intermediate versions of
the Fabric OS you might need. Plan carefully and for extra time if this is your situation.
Faulty CP blade indicators
Confirm that you need to replace the CP blade. The following events might indicate that a CP blade
is faulty:
• The status LED on the CP blade is lit steady amber, or the power LED is not lit.
