specific and detailed process. Read the directions under Downloading firmware from an FTP server on
page 75 or Downloading firmware from a USB device on page 76 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 8510-4 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 Table 10 on page 74
table to see which intermediate versions of the Fabric OS you might need. Plan carefully and for extra
time if this is your situation.
