About this document
This document details procedures for replacing a failed DC power
supply in an HP StorageWorks 2000 Family Modular Smart Array.
Before you begin
CAUTION:
Parts can be damaged by electrostatic discharge. Use proper
anti-static protection:
•Keep the replacement component in the ESD bag until needed
•Wear an ESD wrist strap grounded to an unpainted surface
of the chassis.
•If an ESD wrist strap is unavailable, touch an unpainted surface
of the chassis before handling the component.
•Never touch connector pins.
Verifying component failure
Check the DC Voltage/Fan Fault/Service Required (bottom) LED:
•Amber = Fault condition
Disconnecting a DC power cable
IMPORTANT:
Use only the DC power cables provided with your product.
1. Verify that the main breaker to the rack is shut off prior to
disconnecting any DC connections.
2. Verify that all enclosure power switches are off.
3. Loosen the cable-locking screws attaching the D-shell connector to
the power supply.
4. Disconnect the power cable from the power supply.
5. Turn on the main breaker to the rack.

Installing a DC power supply
1. Slide the module into the slot as far as it will go.
2. Press the latch upward to engage the module; turn the thumbscrews
finger-tight
3. Connect a DC power cable to each power supply using the

positioning before tightening.
4. Tighten the screws at the top and bottom of the shell with a torque
between 1.7 N-m (15 lb-in) and 2.3 N-m (20 lb-in) to attach the
cable securely to the DC power sources.
5. Turn on the main breaker to the rack.
6. Turn on the enclosure power switches.
Verifying component replacement
After replacing the module, check that the Input Power Good LED is on
and the DC Voltage/Fan Fault/Service Required (bottom) LED is off.
