Warranty

The Compaq Prefailure Warranty helps prevent unplanned shutdowns of the system by allowing for the replacement of covered parts before they fail. The warranty covers processors, memory, and hard drives. Compaq Insight Manager, included with the system, must be installed for the Compaq Prefailure Warranty to be in effect.

When Compaq Insight Manager alerts you that a component may be eligible for Prefailure Warranty replacement, follow the onscreen instructions or contact a Compaq authorized service provider in your area. A yellow status indicator on the Compaq Insight Manager control panel signals that a component is in a prefailure condition and should be replaced.

Consult the Compaq Customer Support Center or refer to the Limited Warranty Statement included with your server for details. Certain restrictions and exclusions apply. For additional warranty information, visit the Compaq website at

www.compaq.com/support/

Server Features 1-15

Chapter 2

Overview of Server Installation

The following instructions are provided as an overview for first-time installation of your Compaq ProLiant ML350 Generation 2 server.

WARNING: To reduce the risk of electric shock or damage to the equipment:

■Do not disable the power cord grounding plug. The grounding plug is an important safety feature.

■Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all times.

■Disconnect power from the server by unplugging the power cord from either the electrical outlet or the server.

■Do not place anything on power cords or cables. Arrange them so that no one can accidentally step on or trip over them. Do not pull on a cord or cable. When unplugging from the electrical outlet, grasp the cord by the plug.

CAUTION: Electrostatic discharge (ESD) can damage electronic components. Be sure that you are properly grounded (earthed) before beginning any installation procedure. See Appendix B, “Electrostatic Discharge (ESD),” for more information.

2-2 Compaq ProLiant ML350 Generation 2 Server Setup and Installation Guide

Selecting a Site

Make sure that the installation area that you select has the following features:

■A sturdy, level installation site that includes dedicated and properly grounded (earthed) circuits, air conditioning, and electrostatic discharge (ESD) protection

■7.6 cm (3.0 inches) clearance on all sides of server for proper ventilation in a tower configuration

IMPORTANT: See the following section, “Installing the Rack Server,” for clearance specifications if you are installing the ProLiant ML350 Generation 2 server into a rack configuration.

■A separate electrical circuit for the server

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.

To purchase a UPS, contact your local Compaq authorized reseller or visit the Compaq website:

www.compaq.com/showroom/

Refer to Appendix F, “Specifications,” for detailed power and environmental site requirements.
