diode (LED) description of the Summitª Redundant Power Supply (RPS).

UMMARY OF FEATURES

S

The features of the Summit RPS are as follows:

¥

Provides redundant, load-shared power for up to two Summit Switches.

If the primary power supply for the Summit fails, the Summit RPS takes over,
ensuring uninterrupted network operation.

¥

Contains two active power supplies (each with its own AC power connector) that
share the load with the primary power supply located in the Summit Switches.

¥

Provides status on power supply and fan operation of the RPS by way of the
Summit Switch Simple Network Management Protocol (SNMP) and command-line
interface (CLI).

Information regarding the RPS power supply and fan operation can be obtained by
using the

¥

Uses a standard 2U, 19-inch rack mount.

¥

Has 110/220 VAC autosensing capability.

¥

Capable of driving 3.3V at 20A and 5V at 10A on each of its DC connectors.

¥

Supports only Extreme Networks Summit Switches.

The Summit RPS fan is operating properly.
The Summit RPS fan speed has slowed to 80 percent or less of

full rotational speed and should be replaced.

If the RPS DC cables are not connected to a Summit Switch, but the AC power
cords are connected to an AC outlet, the RPS1 and RPS2 LEDs will blink. If one
of the cables is properly connected to a Summit Switch, but the remaining cable

is not, the unconnected cable will cause its associated RPS LED to blink.
