Redundant and External Power
Introducing the ProCurve 620
External Power Supply
The ProCurve 620 Redundant and External Power Supply is a dual-mode
power supply that can supply backup power to so equipped ProCurve
switches and additional power for Power over Ethernet (PoE) capable
switches.
Figure 1-1. ProCurve 620 Redundant and External Power Supply (J8696A)
Throughout this manual, this unit will be abbreviated as the 620 RPS/EPS.
The 620 RPS/EPS has two redundant power supply (RPS) ports supporting
backup power to two supported ProCurve switches. The 620 RPS/EPS also
has two external power supply (EPS) ports that provide PoE power for up to
two ProCurve PoE switches.
This chapter describes the 620 RPS/EPS including:
■ front of the unit (page 1-2)
■ back of the unit (page 1-4)
■ RPS port operation (page 1-5)
■ EPS port operation (page 1-5)

RPS Ports on the 620 RPS/EPS
The 620 RPS/EPS has two redundant power supply ports. You can connect up
to two ProCurve switch units, and backup power can be supplied to up to two
units.
EPS Ports on the 620 RPS/EPS
The 620 RPS/EPS has two external power supply ports. You can connect one
or two ProCurve PoE capable switches to provide PoE power as a primary or
backup source. Each port receives the maximum power (398 W). Each EPS
port is independent of the other. Therefore if one fails the other can still
provide EPS power.
1-4
Port Status LEDs
The RPS and EPS port status LEDs on the 620 RPS/EPS back panel are a
duplication of those on the front panel. For a description of these LEDs, see
Table 1-1 on page 1-2.
Power Connector
The 620 RPS/EPS does not have a power switch; it is powered on when
connected to an active AC power source. The 620 RPS/EPS automatically
adjusts to any voltage between 100-127 and 200-240 volts and either 50 or 60
Hz. There are no voltage range settings required.
Introducing the ProCurve 620 Redundant and External Power Supply
RPS Port Operation
RPS Port Operation
The 620 RPS/EPS can be connected to two switches through RPS cables. Each
RPS port is independent of the other. Therefore if one fails the other can still
provide RPS power. The unit can provide up to 195 W of power at +12 VDC to
a each switch.
The 620 RPS/EPS is able to detect switches connected to each RPS port and
also the status of their primary AC power supply. The unit supports a hot-plug
feature where switches can be connected or disconnected to the RPS ports
without causing any disruption either to switch operation or the 620 RPS/EPS.
Over-current protection on each RPS port prevents any switch from exceeding
the power supply limit of the unit. Any overload condition causes the 620 RPS/
EPS to shut down the port.
EPS Port Operation
Redundant and External Power
Introducing the ProCurve 620
The 620 RPS/EPS supports two EPS ports that can provide power to PoE
capable switches through EPS cables. Each external power supply unit can
provide PoE power to a switch as a primary source or as a backup to a switch
that has its own internal PoE power supply.
Each EPS port operates individually. The 620 RPS/EPS has two EPS ports that
can provide up to 398 W of PoE power at 50 VDC each. See “Recommended
Connection Topologies” on page 2-11.

Installing and Connecting the ProCurve 620 Redundant and External Power Supply
The 620 RPS/EPS comes with an accessory kit that includes the brackets for
mounting the unit in a standard 19-inch telco rack or in an equipment cabinet,
and rubber feet that can be attached so the unit can be securely located on a
horizontal surface. The brackets are designed to allow mounting the unit in a
variety of locations and orientations.

Installation Procedures
Installation Procedures
Summary
Follow these steps to install the 620 RPS/EPS. The rest of this chapter provides
details on these steps.
1. Prepare the installation site (page 2-5). Make sure the physical envi-
ronment into which the unit will be installed is properly prepared,
including having the correct cabling ready to connect to the unit and
having an appropriate location for the unit. See page 2-4 for installation
precautions.
2. Mount the unit (page 2-5). The unit can be mounted in a 19-inch telco
rack, in an equipment cabinet, or on a horizontal surface.
3. Connect devices to the unit (page 2-8). Using the supplied RPS and
EPS cables, connect the unit to the devices that it will support with
redundant power or PoE power.
4. Connect power to the unit (page 2-9). Once the unit is mounted, plug
it into a nearby main AC power source.

5. Verify the unit is operating correctly (page 2-10). This is a simple
process of observing that the LEDs on the unit’s front panel indicate
correct operation.
At this point, your unit is fully installed. See the rest of this chapter if you need
more detailed information on any of these installation steps.
