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.
