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 13.
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.
