When only one PSU is installed, both "AC OK" and "DC OK" LEDs on the installed PSU must be green
for the FCX device to function normally.
When two PSUs are installed, both "AC OK" and "DC OK" LEDs for one of the installed PSUs must be
green for the FCX device to function normally.
HPOE and HPOE + power supplies
Brocade FCX 624S-HPOE and Brocade FCX 648S-HPOE devices use a 620W PSU. When one PSU
is powering the switch, the HPOE budget is 410W. If both PSUs are installed and powering the switch,
each PSU provides 410W to the switch, increasing the HPOE budget to 820W.
