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 22 shows power supply placement.

In the FSX 1600 chassis, the system power supplies occupy slot numbers 1 – 4 in the top row with
the redundant supplies in slot numbers 3 and 4. The POE power supplies occupy slot numbers 5 –
8 in the bottom row. Figure 23 shows power supply placement.

The installed power supplies provide power to all chassis components, sharing the workload
equally. If a power supply fails or overheats, the failed power supply’s workload is redistributed to
the redundant power supply, if one is present.
