Figure 2.22 Power Supply Placement in the FSX and FSX 800
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
2.23 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.
The power supplies are hot swappable, which means you can remove and replace them without powering down
the system. You can remove and insert a power supply without opening the chassis. If the device contains
redundant 12-volt power supplies, you can remove one of the power supplies without interrupting operation. The
remaining power supply provides enough power for all the ports. For more information about removing and
installing the power supplies, see “Installing or Replacing a Power Supply” on page 7-17.
WARNING: The power supplies are hot swappable, which means they can be removed and replaced while the
chassis is powered on and running. However, Foundry Networks recommends that you disconnect the power
supply from the wall outlet before removing and replacing the supply. The device can be running while a power
supply is being installed or removed, but the power supply itself should not be connected to a power source.
Otherwise, you could be injured or the power supply or other parts of the device could be damaged.
About Replacement Power Supplies
Replacement power supplies for the SX-ACPWR-SYS and SX-ACPWR-POE were introduced with software
release FSX 03.2.00d. The replacement power supplies are functionally equivalent to the original power supplies,
and can be used in combination with the original power supplies in the same chassis. Although the model
numbers for both the newer and older versions of the power supplies are identical, the front of the power supplies
are visually different and the manufacturing part numbers are different.
