Enabling and disabling blades
3
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
1. Connect to the switch and log in as admin.
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, FC8-64, and FC16-48 port blade enabling exceptions
Because the area IDs are shared with different port IDs, the FC8-48, FC8-64, and FC16-48 blades
support only F_ and E_Ports. They do not support FL_Ports.
Port swapping on an FC8-48, FC8-64, and FC16-48 is supported only on ports 0–15. For the
FC8-32 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.
FR4-18i application blade enabling exceptions
Note the following exceptions to enabling the FR4-18i application blade:
• You have inserted the FR4-18i blade into a slot that was previously empty or contained an
FC8-16, FC8-32, FC8-48, FC10-6, FS8-18.
If the FR4-18i blade is operational and the platform is rebooted, then after the successful
bootup of the system the blade continues operations using the previous configurations.
If a previously configured FR4-18i blade is removed and another or the same FR4-18i blade is
inserted into the same slot, then the ports use the previous configuration and come up
enabled. If you do not want to use the previous configuration, you must clear the configuration
information, remove the blade, and then reseat the blade.
If a previously-configured FR4-18i blade is removed and an FC8-16, FC8-32, FC8-48, or
FC10-6 blade is plugged in, then—other than the port’s EX_Port configuration—all the
remaining port configurations previously applied to the FR4-18i ports can be used. The
EX_Port configuration on those ports is disabled before the FC8 port blade becomes
operational. When a blade is present in the slot, then any requested port configuration is
validated against the blade’s capabilities before accepting the request. Also, hot swapping
causes the ports on the FR4-18i to be persistently disabled which later need to be enabled.
• You have turned on the power to the chassis and the FR4-18i blade in that slot was not active
prior to the power-on you must persistently enable the ports manually. For instructions on how
to manually persistently enable a port, refer to “Port activation and deactivation” on page 42.
ATTENTION
The ports of an FR4-18i are persistently disabled only if an FR4-18i was not previously in that
slot. You can replace an FR4-18i with another one with no change in the port states.
