Redundant Power Supplies

The Redundant Power Supply connector on an x610 Series switch rear panel can connect to an optional Redundant Power Supply (RPS), the AT-RPS3000. The RPS can provide power to the switch in the event of a failure of the switch’s internal power supply.

The AT-RPS3000 has slots for two power supply modules. Either the AT-PWR800 (800W) or AT-PWR1200 (1200W) power supply modules can be installed in the RPS.

Warning

Do not hot swap the power supply modules. It is not necessary to power down the RPS before you remove or swap a power supply module. However, always disconnect the AC cord before the power supply module is removed and ensure the power supply module is correctly installed before reconnecting the AC cord.

When fully populated, the RPS can support up to four x610 switches simultaneously, depending on the switches configuration. The RPS can backup one high-power consumption switch or two low-power consumption switches with each power supply module. The 24 port switches are considered low-power consumption switches while the 48 port switches are considered high-power consumption switches. The RPS is not able to identify if the attached switch is a high-power consumption switch or a low-power consumption switch.

The RPS has four connectors on the rear panel, as shown in Figure 28. Connectors 1 and 2 supply power from power supply module A, the right side module, and connectors 3 and 4 supply power from power supply module B, the left side module.

Figure 28. Connectors on RPS

Connectors 1 and 3 supply system power only and connectors 2 and 4 supply system power and extra PoE power. A switch connected to connector 2 will receive extra PoE power only from power supply module A and a switch connected to connector 4 will receive extra PoE power only from power supply module B.
