Chapter 1: Overview
Redundant Power Supplies
The RPS connector on an x600 Series switch rear panel can connect to an optional Redundant Power Supply module. The RPS connector on the x600-24Ts, x600-24Ts/XP, x600-48Ts, or x600-48Ts/XP switch can connect to the optional AT-RPS3204 Redundant Power Supply, shown in Figure 21. The RPS connector on the x600-24Ts-POE switch connects to the optional AT-RPS3104 Redundant Power Supply (not shown). Both RPS units can provide power to their respective switches in the event of a failure of the switch’s internal power supply.
Both Redundant Power Supplies feature one pre-installed Power Supply module and three empty slots for additional power supplies. Each power supply module can support one x600 switch. When fully populated, each RPS unit can support up to four x600 switches simultaneously.
The power supply modules in each Redundant Power Supply are hot swappable with the x600 switches. This means that it is safe to connect a Redundant Power Supply module with its power ON to an x600 switch (which is also powered on) using a 21-pin D-combo connector cable from the module into the RPS connector on the x600 switch.
For information about installing each of the Redundant Power Supply models, consult the documentation shipped with the unit.
The connector pinouts for the AT-RPS3104 redundant power supply are described in “AT-RPS310417-pin Connector Pinouts” on page 108 and the connector pinouts for the AT-RPS3204 redundant power supply’s connector are described in “AT-RPS320421-pinD-combo Port and Connector Pinouts” on page 110.
