AT-RPS9000
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. So, when fully loaded, the AT-RPS9000
chassis can supply up to four switches.
The AT-RPS9000 chassis has two AC power inlets. Each inlet supplies two bays
(that is, each inlet supplies two AT-PWR9000 units and two switches).
Figure 10 on page 23 shows the chassis’s rear panel.

Table 8 on page 22 lists the RPS connector’s pin numbers and pin functions, as
found on the rear panel of AT-9812T and AT-9816GB switches.
