CORE8 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. 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 FC8-16 blades: If you are running Fabric OS v6.0, then you cannot downgrade to earlier versions without removing the blades. Brocade DCX Director with FC8-16/32/48 blades: If you are running Fabric v6.1.0, then you cannot downgrade to pre-Fabric OS v6.0.0 versions as they are not supported on this director.

Blade troubleshooting tips
This chapter refers to the following specific types of blades inserted into either the Brocade 48000
director or Brocade DCX or DCX-4S Backbone:
•
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, slots 6 and 7 on the Brocade DCX, and slots 4
and 5 on the Brocade DCX-4S.
•
CORE8 and CR4S-8 core blades provide ICL functionality between two Brocade DCX
Backbones. CORE8 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.
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 FC8-16 blades:
If you are running Fabric OS v6.0, then you cannot downgrade
to earlier versions without removing the blades.
Brocade DCX Director with FC8-16/32/48 blades:
If you are running Fabric v6.1.0, then you cannot
downgrade to pre-Fabric OS v6.0.0 versions as they are not supported on this director.
