2 Blade swapping 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 enable the ports manually. For instructions on how to manually enable a port, refer to "Port activation and deactivation" on page 28. ATTENTION FR4-18i is disabled upon hot-plug. To summarize: • When an FC4-16, FC4-32, FC8-16, FC8-32, FC10-6, FC4-16IP, FA4-18, 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. • When an FR4-18i blade is replaced by an FC4-16, FC4-32, FC8-16, FC8-32, or FC10-6 blade, then the EX_Port configuration is removed from any ports that were configured as EX_Ports (equivalent to disabling the EX_Port configuration using the portCfgEXPort command). All remaining port configurations are retained. NOTE This is not true for the 8Gbps port blades. Since FC8 type blades support EX_Ports, they are still retained in the configuration, but the ports are persistently disabled. Disabling blades 1. Connect to the switch and log in as admin. 2. Enter the bladeDisable command with the slot number of the port blade you want to disable. ecp:admin> bladedisable 3 Slot 3 is being disabled Blade swapping Blade swapping allows you to swap one blade with another of the same type; in this way, you can perform a FRU replacement 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 enterprise-class platform. If an error is encountered then blade swap quits without disrupting traffic flowing through the blades. If an 34 Fabric OS Administrator's Guide 53-1001336-01
