Operating Rules
This chapter discusses the operating rules and characteristics of PoE and
describes the capabilities of a device used to provide redundant and external
PoE power, the HP ProCurve 600 Redundant and External Power Supply
(J8168A), hereafter referred to as the HP 600 RPS/EPS. The HP 600 RPS/EPS
is an accessory product for the Switch 2600-PWR Series devices, the HP
ProCurve Switch xl PoE Module, and specific other HP ProCurve switches.
The redundant power supply (RPS) and external power supply (EPS) features
are explained below.
HP 600 RPS/EPS Operation
The HP 600 RPS/EPS monitors the power signal from a switch by detecting
that it is connected to the switch with an RPS or EPS cable. When the power
from the switch is no longer detected, the HP 600 RPS/EPS provides power to
the switch within 1 millisecond.
The HP 600 RPS/EPS supports hot plugging of an RPS or EPS cable. For more
information refer to the documentation that came with the HP 600 RPS/EPS.
For connectivity refer to the HP ProCurve Switch 2600 and 2600-PWR Series
Installation and Getting Started Guide that came with your switch.
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.
