Introducing the HP ProCurve 600/610 External Power Supplies
Back of the Unit
Port Status LEDs
The RPS and EPS port status LEDs on the HP 600 RPS/EPS back panel are a
duplication of those on the front panel. Similarly, the backup power port status
LEDs on the HP 610 EPS back panel are a duplication of those on the front
panel. For a description of these LEDs, see
Table 1-1 on page
1-3.
Internal Power Status LED
The Internal Power Status LED on the HP 610 EPS back panel is a duplication
of the one on the front panel. For a description of this LED, see
Table 1-1 on
page
1-3.
EPS Backup Power Ports
The HP 610 EPS has two backup power ports that allow up to five EPS units
to be connected together and thereby provide backup power to a failed unit.
However, note that the power load on the remaining active units must be
limited so that there is still enough reserve power to support a failed unit. The
simplest way is to have one unit in the group that has no direct PoE load on
it. Sample topologies are shown at the end of
chapter 2
in this book.
Power Connector
The HP 600 RPS/EPS and HP 610 EPS do not have a power switch; they are
powered on when connected to an active AC power source. The HP 600 RPS/
EPS automatically adjusts to any voltage between 100--240 volts and either 50
or 60 Hz, and the HP 610 EPS between 110--240 volts and either 50 or 60 Hz.
There are no voltage range settings required.
In addition, the HP 610 EPS may be powered on when receiving power
through a backup power port even when not connected to an active AC power
source.
C a u t i o n
The power cords supplied for the HP 600 RPS/EPS may be of a lower amperage
rating than those supplied for the HP 610 EPS. For safe operation, only use
the AC power cord that is supplied with the HP 610 EPS.
