Blade troubleshooting tips
This chapter refers to the following specific types of blades inserted into the Brocade DCX, DCX-4S,
and DCX 8510 family enterprise-class platforms:
• FC blades or port blades contain only Fibre Channel ports: Brocade
FC8-16/32/32E/48/48E/64 and FC16-32/48.
• AP blades contain extra processors, some with specialized ports, and have the Fabric OS code
downloaded to them automatically in the chassis: FX8-24, FS8-18, and FCOE10-24.
• CP blades have a control processor (CP) used to control the entire switch; they can be inserted
only into slots 6 and 7 on the Brocade DCX and DCX 8510-8, and slots 4 and 5 on the Brocade
DCX-4S and DCX 8510-4.
• CR8 and CR4S-8 core blades provide ICL functionality between two Brocade DCX Backbones.
CR8 blades can be inserted only into slots 5 and 8 on the Brocade DCX. CR4S-8 blades can be
inserted only into slots 3 and 6 on the Brocade DCX-4S.
• CR16-8 and CR16-4 core blades provide ICL functionality between two Brocade DCX 8510
Backbones. CR16-8 blades can be inserted only into slots 5 and 8 on the Brocade DCX
8510-8. CR16-4 blades can be inserted only into slots 3 and 6 on the Brocade DCX 8510-4.
Typically, issues detected during firmware download to AP blades do not require recovery actions
on your part.
If you experience frequent failovers between CPs that have different versions of firmware, then you
may notice multiple blade firmware downloads and a longer startup time.
Symptom Relocation of internal image times out on CP8 control processor blade.
Probable cause and recommended action
This can be caused by issues in the co-CPU. If this happens, the firmware download process
synchronizes the partitions in the main-CPU and co-CPU by starting a firmware commit operation.
Wait at least 15 minutes for the commit operation to complete, issue the firmwareShow command
to verify the partitions are synchronized, and reissue the firmwareDownload command. If the
problem persists, you must contact the switch service provider.
