Power specifications for POE

The implementation of the 802.3af standard limits power to 15.4W (44V to 57V) from the power
sourcing device. This limit complies with safety standards and existing wiring limitations. Though
limited by the 802.3af standard, 15.4 watts of power is ample, as most powered devices consume
an average of 5 to 12 watts of power. IP phones, wireless LAN access points, and network
surveillance cameras each consume an average of 3.5 to 9 watts of power.
Brocade 48-volt 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 48-volt power
supply can support depends on the number of watts required by each device. Each 48-volt power
supply provides 410 watts of power for POE, 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 FWS consumes 12 watts of power, one 48-volt supply will power up to 34 POE
ports.
If your FastIron WS chassis has 48 ports, and each POE-enabled port needs 15.4 watts, then a
maximum of 26 ports can supply power to connected devices.
For power supply specifications, refer to
configuration procedures, refer to the FastIron Configuration Guide.
