AT-RPS3204 Redundant Power Supply

The RPS connector on the back panel of the switch connects to the optional AT-RPS3204 redundant power supply unit, shown in Figure 14. The unit can provide power to the switch in the event that the switch’s internal power supply fails.

The AT-RPS3204 redundant external power supply features one preinstalled AT-PWR3204 Power Module and three empty slots for additional power modules. Each power module can support one switch. When fully populated with AT-PWR3204 Power Modules, the AT-RPS3204 unit can support up to four switches simultaneously. For information about installing an AT-RPS3204 unit, consult the documentation shipped with the unit.
