Operating Rules

Redundant Switch Power

Redundant Switch Power
The HP 600 RPS/EPS provides redundant power to any one of up to six switch
products, to back up the power supply in a switch in case of loss of AC power,
or a fault condition. The HP 600 RPS/EPS is an unmanaged power supply that
only provides information by way of LEDs or through the port interfaces to
attached devices.

Operating Characteristics

The HP 600 RPS/EPS has six RPS ports, each of which can provide redundant
+12V power to a connected switch, but only one port can provide this power
at a given time. If a switch with no AC power is connected to an operating HP
600 RPS/EPS, it will receive power if power is available (no higher priority
port is already using the RPS power).
