Enabling and disabling blades

Port blades are enabled by default. In some cases, you will need to disable a port blade to perform
diagnostics. When diagnostics are executed manually (from the Fabric OS command line), many
commands require the port blade to be disabled. This ensures that diagnostic activity does not
interfere with normal fabric traffic.
If you need to replace an application blade with a different application blade, there may be extra
steps you need to take to ensure that the previous configuration is not interfering with your new
application blade.

The iSCSI function over FCIP is not supported, but the FCIP link is the same as other FC E_Ports. This is not
Not compatible with other application blades or with the FC8-64 in the same chassis.
The hardware limit is enforced by software.
The FR4-18i and Brocade 7500 GbE ports cannot be connected to either the FX8-24 or
Brocade 7800 GbE ports. The ports may come online, but they will not communicate with each
other. Running physical cables between the FR4-18i and FX8-24 blades is not supported.
The port configuration is maintained separately for the GbE ports of the FR4-18i and FX8-24
blades. The port configuration data of one blade is never applied to the other type even if an
FX8-24 replaces an FR4-18i in the same slot of a chassis. However, if an FR4-18i blade is
replaced with an FX8-24 blade and then replaced back with an FR4-18i, the FR4-18i previous
IP configuration data would be applied to the new FR4-18i. The same behavior applies if you
were to replace the FX8-24 with an FX8-24.
When Virtual Fabrics is disabled, replacing an FR4-18i with an FX8-24 (and vice-versa) is
allowed without any pre-conditions
When Virtual Fabrics is enabled (regardless of whether the FR4-18i or FX8-24 blade is in the
default switch), replacing an FR4-18i with an FX8-24 (and vice-versa) without rebooting or
power cycling the chassis will fault the blade with reason code 91. However, after blade
removal, if you reboot or power cycle the chassis, inserting the other blade type is allowed.
The data paths in both blades are interoperable between FC ports. FR4-18i FC ports can
stream data over FX8-24 GbE ports and vice versa.
The FX8-24 and FS8-18 blades cannot co-exist with the FCOE10-24 blade.
