2-4 Compaq ProLiant ML330e/ML330 Server Maintenance and Service Guide

Preparation Procedures

WARNING: Only authorized technicians trained by Compaq should attempt to repair this

equipment. Because of the complexity of the individual boards and subassemblies, no one

should attempt to make repairs at the component level or to make modifications to any printed

wiring board. Improper repairs can create a safety hazard.

CAUTION: Electrostatic discharge (ESD) can damage electronic components. Be sure that you

are properly grounded (earthed) before beginning any installation procedure. See “Electrostatic

Discharge Information” earlier in this chapter for more information.

Powering Down the Server

Before beginning any removal and replacement procedure:

1. Open the drive bay door on the front bezel.

2. Power down the ProLiant ML330e/ML330 server by pressing the power button on the

front of the server.

IMPORTANT: To completely remove all power from the ProLiant ML330e/ML330 server, you must

disconnect the power cord. The front panel power button may not completely shut down power to the

server.

3. Disconnect and remove the AC power cord from the AC outlet, and then from the

ProLiant ML330e/ML330 server.

4. Disconnect any other external equipment connections to the server.

Server Warnings and Precautions

WARNING: To reduce the risk of injury from electric shock, disconnect all power cords to

completely remove power from the system.

WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal system

components to cool before touching them.

CAUTION: Protect the server from power fluctuations and temporary interruptions with a

regulating uninterruptible power supply (UPS). This device protects the hardware from damage

caused by power surges and voltage spikes, and keeps the system in operation during a power

failure.

CAUTION: The ProLiant ML330e/ML330 server must always be operated with system unit

covers on. Proper cooling is not achieved when the system unit covers are removed.
