number of watts required by each power-consuming device. Each 52- 54-volt power supply can provide a maximum of
1080 watts of PoE power, and each PoE port supports a maximum of 15.4 watts of power per PoE power-consuming
device. For example, if each PoE power-consuming device attached to the Brocade device consumes 15.4 watts of power,
one 52- 54-volt supply will power up to 70 PoE ports. You can install a second 52-54-volt supply for additional PoE
power.

The 52- 54-volt (220-volt input only) PoE power supplies provide power to the PoE daughter card, and ultimately to PoE
power-consuming devices. The number of PoE power-consuming devices that one 220-volt power supply can support
depends on the number of watts required by each power-consuming device. Each 220-volt power supply can provide a
maximum of 2260 watts of PoE power, and each PoE port supports a maximum of 15.4 watts of power per PoE power-
consuming device. For example, if each PoE power-consuming device attached to the Brocade device consumes 15.4
watts of power, one 220-volt supply will power up to 146 PoE ports. You can install a second 220-volt supply for
additional PoE power.

NOTE

The system activates as many PoE ports as the 52- 54-volt PoE power supplies can handle. The system calculates the
maximum number of PoE ports it can support based on the number of PoE power supplies installed. PoE ports are enabled
based on their priority settings. The system reserves the maximum configured power per PoE-enabled port, even if the PoE
power-consuming device is drawing less power.

PoE+ devices (SX-FI48GPP and SX-FI-24GPP):

NOTE

The SX-FI624P module does not support PoE+ and 802.3at applications.

The 12-volt AC and DC power supplies (also called system (SYS) power supplies) provide power to the management
module, all non-PoE interface modules (if applicable), and all ports on PoE+ modules that do not require PoE power or to
which no power-consuming devices are attached. In the FSX 800, you can install a second 12-volt power supply for
redundancy. The FSX 1600 comes with and requires two 12-volt power supplies and supports up to four 12-volt power
supplies for redundancy.

The 52- 54-volt PoE+ power supplies provide power to the PoE+ daughter card, and ultimately to PoE+ power-consuming
devices. The number of PoE+ power-consuming devices that one 52- 54-volt power supply can support depends on the
number of watts required by each power-consuming device. Each 52- 54-volt power supply can provide a maximum of
1080 watts of PoE power, and each PoE+ port supports a maximum of 30 watts of power per PoE+ power-consuming
device. For example, if each PoE+ power-consuming device attached to the Brocade device consumes 30 watts of power,
one 52- 54-volt supply will power up to 36 PoE+ ports. You can install a second 52- 54-volt supply for additional PoE+
power.
