The RPS can be the only source of PoE power for the switch or the RPS
can boost the PoE power available from the primary power source, the
power supply module installed in the switch. If the switch does not receive
PoE power from its primary power supply, the available PoE power
depends on the PoE rating of the associated power supply module in
RPS. If the switch is able to get PoE power from both primary power
supply and RPS, the primary power supply and the power supply module
installed in the RPS will share the PoE load.
For information about installing the RPS, consult the documentation
shipped with the unit.
The connector pinouts for the AT-RPS3000 redundant power supply are
described in “AT-RPS3000 21-pin Connector Pinouts” on page 118.
