Using a ProCurve 620 Redundant Power Supply

The ProCurve 620 Redundant and External Power Supply (J8696A) is an
accessory product for the Series 3500yl switch. The power supply provides
two types of power to the switches:
■ Redundant power to two switches to back up the internal power
supply in case of AC power loss or a fault condition. Should the
internal power supply fail, power will be supplied from the
620 RPS/EPS.
■ External PoE power to up to two switches. The 620 RPS/EPS can
supply 398 watts of PoE power to the switch if the internal power
supply should fail. For the ProCurve 3500yl-48G-PWR the external
PoE power is additional power made available to the switch's ports.
The 620 RPS/EPS has two RPS ports, each of which can provide redundant
+12V power to a connected switch. If a switch with no AC power is connected
to an operating 620 RPS/EPS, it will not receive power. The switch must first
be powered on, then connected to the 620 RPS/EPS.
The 620 RPS/EPS also has two EPS ports. The 620 RPS/EPS can provide a
maximum of 398 watts of PoE power to each of the two EPS ports.
For further information regarding the 620 RPS/EPS PoE capabilities, 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
