AT-9400Ts Stack Installation Guide

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 8.

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-PWR3202 Power Module and three empty slots for

additional power modules. Each power module can support one switch.

When fully populated with AT-PWR3202 Power Modules, the

AT-RPS3204 unit can support up to four switches, simultaneously. For

information about installing an AT-RPS3204 unit, consult the

documentation that ships with the unit.
