Redundant Power Supply (RPS)

AT-8600 Series switches have a Redundant Power Supply (RPS) connector on
their rear panel. The RPS connector differs for different switch models.
For information about the RPS for AT-8624T/2M and AT-8648T/2SP switches,
Figure 5 illustrates the pin layout to the 16-pin molex connector and RPS port.
Table 1 lists the connector's pin numbers and pin functions.
For information about the RPS for the AT-8624PoE switch,
lists the connector's pin numbers and pin functions.
