Installing and Connecting the HP Redundant / External Power Supplies

Installation Procedures

Installation Precautions:

Follow these precautions when installing your RPS/EPS power supply:

WARNINGS ■ The rack or cabinet should be adequately secured to prevent it

from becoming unstable and/or falling over.

Devices installed in a rack or cabinet should be mounted as low as

possible, with the heaviest devices at the bottom and progressively

lighter devices installed above.

■ Do not use power cord, part number 8120-5337 or 8120-5342, with

the HP 610 EPS. A power cord with a minimum wire gauge of

14 Awg is required to prevent overloading of the power cord. (This

applies to voltages of less than 127 volts.)

Cautions ■ If the HP 630 RPS/EPS is to be shipped in a rack, be sure to use only an

HP 10K rack with a shock pallet. Mount the HP 630 RPS/EPS using an HP

ProCurve 1U Rack Mount kit part number 356578-B21 and (if shipping a

single HP 630 RPS/EPS unit) Half-width Filler kit P/N 5064-2163. Both kits

must be used. Otherwise you will void the warranty. If shipping two RPS/

EPS units, then only the HP networking 1U Rack Mount kit is necessary.

The HP 630 RPS/EPS must be supported from underneath either by an HP

switch or by an HP Rack Support shelf kit part number AB469A.

■ Make sure the power source circuits are properly grounded, then use the

power cord supplied with the unit to connect it to the power source.

■ If your installation requires a different power cord than the one supplied

with the unit, be sure the cord is adequately sized for the unit’s current

requirements. Be sure to use a power cord displaying the mark of the

safety agency that defines the regulations for power cords in your country.

The mark is your assurance the power cord can be used safely with the

unit.

■ When installing the unit, note that the AC outlet should be near the unit

and should be easily accessible in case the unit must be powered off.

■ Ensure the unit does not overload the power circuits, wiring, and over-

current protection. To determine the possibility of overloading the supply

circuits, add together the ampere ratings of all devices installed on the

same circuit as the unit and compare the total with the rating limit for the

circuit. The maximum ampere ratings are usually printed on devices near

the AC power connectors.
