Redundant Power Supply (RPS)
Redundant Power Supply (RPS) units enhance network reliability by
providing backup coverage for switch Power Supply Units (PSUs).
AT-9800 Series switches have an RPS connector on the rear panel. The
connector allows the switch to be connected to an AT-RPS9000 system. The
AT-RPS9000 must be purchased separately.
The AT-RPS9000 is a chassis that holds up to four removable AT-PWR9000
power units. Each AT-PWR9000 power unit can provide redundant power to
one AT-9812T or AT-9816GB switch. When fully loaded, the AT-RPS9000
chassis can support up to four switches.
The AT-RPS9000 chassis has two AC power inlets. Each inlet supplies two
bays, and therefore two AT-PWR9000 units and two switches.

Series switches are shown in the following figure and table.
