Console Port Use the console port (9-pin, “D” type connector) for connecting a terminal and

Redundant Power
Supply Port
The redundant power supply (RPS) port is used to connect to the AT-RPS1000, the
RPS unit that provides a redundant power source to the switch. If the primary power
source for the switch fails, the RPS takes over, ensuring uninterrupted network
operation.
In addition, when connected to the AT-RPS1000, the switch can provide status on
power and fan operation of the redundant power supply module through SNMP and
the command-line interface. The RPS can simultaneously provide power for up to
two switches.
Contact your Allied Telesyn representative for the AT-RPS1000’s availability.
