Installation Procedures
9. (Optional) Connect a 620 Redundant Power Supply
The ProCurve 620 Redundant and External Power Supply, (J8696A), hereafter
referred to as the 620 RPS/EPS, is an accessory product for the Series 3500yl
and 6200yl switches and specific other ProCurve switches. The 620 RPS/EPS
provides two types of power to the switches:
■
■
The 620 RPS/EPS is an unmanaged power supply that only provides informa-
tion by way of LEDs.
RPS/EPS Operation
The RPS/EPS monitors the power signal from the switch by detecting that the
RPS/EPS is connected to a valid switch with an RPS/EPS cable. When the
power from the switch is no longer detected, the RPS/EPS will turn on and
provide power to the switch within 1 millisecond.
The RPS/EPS supports hot plugging of the RPS cable only, Hot disconnect of
the EPS (PoE power) cable is not supported, and could cause loss of power
to the switch. The EPS cable can be connected at any time. The RPS/EPS unit
must be powered down in order to unplug the EPS (PoE power) cable, if power
is flowing.

to the switch
Redundant power to two switches, to back up the internal switch power
supply in case of AC power loss, or a fault condition. Should the internal
switch power supply fail, power will be supplied from the 620 RPS/EPS.
External Power-over-Ethernet (PoE) power to up to two switch products.
The 620 RPS/EPS can supply 398 watts of PoE power to the switch if the
internal PoE power supply should fail. For the Switch 3500yl-48G-PWR
the external PoE power is additional power made available to the switch's
ports. For further information regarding the 620 RPS/EPS PoE capabili-
ties, see the ProCurve Power over Ethernet (PoE) for zl and yl Products
Planning and Implementation Guide and the ProCurve 620 Redundant
and External Power Supply Installation and Getting Started Guide,
which are on the ProCurve Web site at www.procurve.com.
