Power module failure

Fixed power module failure

The S5800-56C, S5800-56C-PWR, S5800-32C-PWR, and S5800-32C switches use fixed power
modules, and support three power input modes: AC input, RPS DC input, and concurrent AC and RPS DC
inputs.
You can look at the system status LED and the RPS status LED of the switch to identify a power system
failure.
