AT-RPS9000
The AT-RPS9000 is a chassis that holds up to four removable AT-PWR9000 RPS
units. To provide backup power to AC versions of AT-9812T and AT-9816GB
switches, each switch must be connected to an AT-PWR9000 RPS unit, and the
RPS unit must be installed in an AT-RPS9000 chassis.
Table 8 on page 22 lists the RPS connector’s pin numbers and pin functions, as
found on AT-9812T and AT-9816GB switches.
Figure K-1 on page 23 illustrates the connector’s pin layout for AT-9812T and
AT-9816GB switch models.
