AT-9400 Series Gigabit Ethernet Switches 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 14.

The unit can provide power to the switch in the event that the switch’s

internal power supply fails.

Note

The AT-9424T/POE switch does not have a RPS connector on its

back panel and is not supported by the AT-RPS3204 Redundant

Power Supply.

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.

connector are described in “RPS 21-pin D-combo Port and Connector

Pinouts” on page 81.
