Choosing a Power Supply Module
Here are a few suggestions on how to choose the power supply modules
for the x610 Series switches and AT-RPS3000 Chassis.
Non-PoE+
Switches
You may use any of the three available power supply modules listed in
Table 1 on page 19, even the two PoE+ modules, in the AT-RPS3000
Chassis to provide active system power to non-PoE+ switches. The
switches may be connected to any of the four RPS connectors on the
chassis.
A power module can support two low-power switches or one high-power
switch. For more information, refer to “Low-power and High-power
Switches” on page 24.
Here is an example. If you have five low-power and two high-power non-
PoE+ x610 Series switches, you would need five power modules, of any
model, and three chassis. The five low-power switches would need three
modules and the high-power switches two modules. The power modules
can be the same model, such as all AT-PWR800 Modules, or different
models.
