AT-RPS8000
The AT-RPS8000 is a chassis that holds up to four removable AT-PWR8000 RPS
units. To provide backup power to AC versions of AT-9812TF and AT-9816GF
switches, each switch must be connected to an AT-PWR8000 RPS unit, and the
RPS unit must be installed in an AT-RPS8000 chassis.
Table 8 on page 22 lists the RPS connector’s pin numbers and pin functions, as
found on AT-9812TF and AT-9816GF switches.
Table 9 on page 22 illustrates the connector’s pin layout, as found on the rear
panel of AT-9812TF and AT-9816GF switches.
Pin 16 is at the connector’s top left, while pin 1 is at its lower right.
