FIGURE 21 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.
For more information about removing and installing the power supplies, refer to “Installing or
replacing a power supply” on page 122.
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.
Figure 22 shows a side-by-side comparison of the SX-ACPWR-SYS replacement power supply and
the original power supply.
