installed. Brocade FCX 624S, FCX 648S, FCX 624S-F, FCX 624-E, FCX 624-I, FCX 648-E and FCX
648-I devices use a 210W PSU. Brocade FCX 624S-HPOE and Brocade FCX 648S-HPOE devices use

LEDs for easy monitoring and troubleshooting.
A secondary power supply can be installed to provide backup power in case of a failure and for load-
balancing when both power suppies are operational.Load-balancing gives the power supplies a longer
life span. Both 210W and 620W PSUs are hot-swappable.
