Features
The AT-RPS3000 Chassis is a modular power supply system for the x610 
Series of Layer 3 Gigabit Ethernet switches. It protects the switches from 
power supply failures and provides additional PoE+ power.
The chassis can support two or four x610 Series switches, depending on 
the switch model. It has two slots for power supply modules, an LED panel 
for viewing the status of the power modules, and four RPS connectors.
As explained in this overview, the power supply modules in the chassis 
function in either a redundant or an active state, depending on the switch 
model. For non-PoE+ x610 Series switches, the chassis acts as the active 
power source for the switches, whose own internal, non-removable power 
supplies function as backup modules. For PoE+ switches, the chassis acts 
as a redundant power supply for system power and in a load-sharing 
mode for PoE+ power.
Warning
The AT-RPS3000 Chassis is designed specifically for the x610 
Series of Layer 3 Gigabit Ethernet switches and should not be used 
with any other product.
Note
The AT-RPS3000 Chassis is not a battery backup unit. The power 
supply modules in the chassis have to be connected to active power 
sources to deliver power to the switches.
LED Panel
The front panel of the AT-RPS3000 Chassis has an LED panel that 
displays status information about the power supply modules and RPS 
ports. The LEDs are described in “LEDs” on page 42.
