detected first, then any subsequently-detected FCOE10-24 blades are faulted. Blades are powered up
starting with slot 1.
In the Brocade DCX 8510-4, if an FCOE10-24 blade is detected, it is faulted under any circumstance.
FX8-24 compatibility
Follow these guidelines when using an FX8-24 in the Brocade DCX and DCX-4S Backbones:
• 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.
• If an FX8-24 blade is replaced by another FX8-24 blade, the previous IP configuration data would be
applied to the new FX8-24.
• The FX8-24 and FS8-18 blades cannot coexist with the FCOE10-24 blade.
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.
Enabling blades
Use the following procedure to enable a blade.
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the bladeEnable command with the slot number of the port blade you want to enable.
ecp:admin> bladeenable 3
Slot 3 is being enabled
48-port and 64-port blade enabling exceptions
Because the area IDs are shared with different port IDs, the 48-port and 64-port blades support only
F_Ports and E_Ports. They do not support FL_Ports. (FL_Ports are not supported on any of the 16-
Gbps blades.)
Port swapping is not supported on 48-port and 64-port blades. For the 32-port blades, port swapping is
supported on all 32 ports. This means that if you replace a 32-port blade where a port has been
swapped with a 48-port blade, the 48-port blade faults. To correct this, reinsert the 32-port blade and
issue portSwap to restore the original area IDs.
Disabling blades
Use the following procedure to disable a blade.
