FastIron Hardware Installation Guide for the FSX, FSX 800, and FSX 1600

The following power supplies can be installed in the FastIron X Series chassis devices:
• Non-POE devices:
• The 12-volt AC and DC power supplies (also called system (SYS) power supplies) provide power to one
management module and up to eight non-POE interface modules. In the FSX and 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.
• POE devices:
• 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 and 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 48-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 48-volt power supply can
support depends on the number of watts required by each power-consuming device. Each 48-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 Foundry device consumes 15.4 watts of power, one 48-volt supply will power up to
70 POE ports. You can install a second 48-volt supply for additional POE power.
• The 48-volt (220-volt input only) POE power supplies (added in release 03.5.00) 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 2160 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 Foundry device consumes
15.4 watts of power, one 220-volt supply will power up to 140 POE ports. You can install a second 220-
volt supply for additional POE power.
NOTE: The system powers on as many POE ports as the 48-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. Keep in mind that the system will
reserve the maximum configured power per POE-enabled port, even if the POE power-consuming device is
drawing less power.
CAUTION: The POE power supply is designed exclusively for use with the FastIron X Series POE devices. The
power supply produces extensive power to support 802.3af applications. Installing the power supply in a device
other than the FastIron X Series POE will cause extensive damage to your equipment.
All power supplies are auto-sensing and auto-switching.
The power supplies are installed in the slots along the bottom of the chassis.
In the FSX and FSX 800 chassis, the 12-volt (system) power supplies occupy slot numbers 3 and 4 on the right,
with the redundant supply in slot 4. The POE power supplies occupy slot numbers 1 and 2 on the left. Figure 2.22
shows power supply placement.
