In the FSX 1600 device, 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 16 Power supply placement in the FSX 1600
Installed power supplies provide power to all device components, sharing the workload equally. If a
power supply fails or overheats, the workload for the failed power supply is redistributed to the
redundant power supply, if one is present.
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 device. 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.
DANGER
The power supplies are hot swappable, which means they can be removed and replaced while
the device is powered on and running. However, it is recommended that you always 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.
Replacement power supplies
Replacement power supplies for the SX-ACPWR-SYS and SX-ACPWR-PoE are functionally equivalent
to the original power supplies, and can be used in combination with the original power supplies in the
same device. Although the model numbers for both the newer and older versions of the power supplies
are identical, the front panels and the manufacturing part numbers are different.
