Power supply usage
The Brocade ICX 7250 models support specific AC power supply inputs and a number of PoE and PoE+ ports with an internal power supply.
Note: Depending on the configuration, each
EPS4000 connection from the device to the
EPS4000 can add 24 ports of PoE (Class 3) or 12 ports of PoE+ power (54-volt supply) in addition
to the internal power supply by providing system power backup. If the overall PoE
requirement is less than the power budget of 370 W (or 740 W), the device can support
24 (or 48) PoE ports. The system power (12-volt supply) portion of the
EPS4000 can be used for internal system power redundancy.
