They can be inserted only into slots 5 and 8 on the Brocade DCX. 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.

Blade troubleshooting tips
This chapter refers to the following specific types of blades inserted into either the Brocade 48000
director or Brocade DCX:
•
FC blades or port blades contain only Fibre Channel ports: Brocade FC4-16/32/48, FC10-6,
and FC8-16/32/48.
•
AP blades contain extra processors and specialized ports: Brocade FR4-18i and FC4-16IP, and
FA4-18.
•
CP blades have a control processor (CP) used to control the entire switch. They can be inserted
only into slots 5 and 6 on the Brocade 48000, and slots 6 and 7 on the Brocade DCX.
•
CR8 core blades provide ICL functionality between two DCX directors. They can be inserted
only into slots 5 and 8 on the Brocade DCX.
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.
ATTENTION
Brocade 48000 with FR4-18i blades:
If you are running v5.1.0 firmware, then you cannot
downgrade to earlier versions without removing the blades.
Brocade 48000 with FC4-48 or FC4-16IP blades:
If you are running Fabric OS v5.2.0, then you
cannot downgrade to earlier versions without removing the blades.
Do not remove blades until the EX_Ports are removed first. The
firmwareDownload
command will
indicate when the blades are safe to remove.
