Enabling and disabling blades 3 FA4-18 application blade enabling exceptions The Brocade 48000 director supports up to two FA4-18 blades in a chassis. The Brocade DCX and DCX-4S Backbones support up to four FA4-18 blades in a chassis. FC4-48 and FC8-48 port blade enabling exceptions Because the area IDs are shared with different port IDs, the FC4-48 and FC8-48 blades support only F_ and E_Ports. They do not support FL_Ports. Port swapping on an FC4-48 or FC8-48 is supported only on ports 0-15. For the FC8-32 port blade, 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 FA4-18, FC4-16IP, FC4-48, 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 FC4-48, 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 FC4 or 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. NOTE The FC4-16IP blade is not supported in either the Brocade DCX or DCX-4S enterprise-class platform. • 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. To summarize: • When an FC4-16, FC4-32, FC8-16, FC8-32, FC10-6, FC4-16IP, FA4-18, FS8-18, or FX8-24 blade is replaced by an FR4-18i blade, the current port configuration continues to be used, and all ports on the FR4-18i blade are persistently disabled.
