Control processor blade (CP8) removal and replacement
This document describes how to remove and replace a control processor (CP8) blade. Each chassis
has two CP8 blades. In the DCX 8510-8, they are located in slots 6 and 7.
NOTE
The CP8 blade is compatible only with the Brocade DCX Backbones (including the DCX 8510
Backbones).
NOTE
The Brocade 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
page 89 or
Downloading firmware from a USB device
on page 90 carefully.
NOTE
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 perform 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.
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:
• Electrostatic discharge (ESD) grounding strap
• Workstation computer
• Serial cable
• IP address of an FTP server for backing up the Brocade DCX 8510-8 configuration
• #2 Phillips screwdriver
• Replacement Brocade DCX 8510-8 control processor blade (CP8)
If you are upgrading through multiple versions of the Fabric OS, consult the
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 may 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.
• The CP blade does not respond to Telnet commands, or the serial console is not available.
• The
slotShow
command does not show that the CP blade is enabled.
