Preface

Precautions

Follow the procedures listed below to ensure safe handling of components and to prevent harm to yourself and the NetServer.

WARNING The HP NetServer LH 3r weighs up to 160 pounds (73 kg.) when fully loaded. If you are removing the LH 3r from the rack, remove the power supplies and hard disk drives before doing so. Follow all local regulations when lifting the NetServer.

To prevent the rack enclosure from tipping over,

∙ Extend the anti-tip foot on the rack

∙ Verify that the leveling feet on the rack are lowered

∙ Do not extend more than one piece of equipment at once

Before removing the cover, always disconnect the power cord and unplug telephone cables. Disconnect the power cord to avoid exposure to high energy levels that may cause burns when parts are short-circuited by metal objects, such as tools or jewelry. Disconnect telephone cables to avoid exposure to shock hazard from telephone ringing devices.

Note that the power switch does not turn off the standby power. Disconnect the power cord to turn off standby power. If the backlight on the LCD display is on, standby power is still on.

CAUTION Never operate this NetServer without first installing all covers and the front bezel. Operating the system without all covers in place reduces critical cooling airflow over some components, such as hard disk drives and processor modules. Operating the system without all covers in place may result in failure of these components.

Wear a wrist strap and use a static-dissipating work surface connected to the chassis at all times to prevent possible static electricity damage to the NetServer components.
