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
FC8-48, FC8-48E, FC8-64, and FC16-48 port blade enabling exceptions
Because the area IDs are shared with different port IDs, the FC8-48, FC8-48E, FC8-64, and
FC16-48 blades support only F_ and E_Ports. They do not support FL_Ports.
Port swapping on an FC8-48, FC8-48E, FC8-64, and FC16-48 is supported only on ports 0–15. For
the FC8-32, FC8-32E, and FC16-32 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 on ports 16–31 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 to ports 16–31.
Disabling blades
Use the following procedure to disable a blade:
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the bladeDisable command with the slot number of the port blade you want to disable.

Blade swapping
Blade swapping allows you to swap one blade with another of the same type; in this way, you can
replace a FRU with minimal traffic disruption. The entire operation is accomplished when the
bladeSwap command runs on the Fabric OS. The Fabric OS then validates each command before
actually implementing the command on the Backbone. If an error is encountered, the blade swap
quits without disrupting traffic flowing through the blades. If an unforeseen error does occur during
the bladeSwap command, an entry will be made into the RASlog and all ports that have been
swapped as part of the blade swap operation will be swapped back. On successful completion of
the command, the source and destination blades are left in a disabled state, allowing you to
complete the cable move.
Blade swapping is based on port swapping and has the same restrictions:
• Shared area ports cannot be swapped.
• Ports that are part of a trunk group cannot be swapped.
• GbE ports cannot be swapped.
• Swapping ports between different logical switches is not supported. The ports on the source
and destination blades must be in the same logical switch.
• Undetermined board types cannot be swapped. For example, a blade swap will fail if the blade
type cannot be identified.
