Electrostatic Discharge Information

A discharge of static electricity can damage static-sensitive devices or microcircuitry. Proper packaging and grounding techniques are necessary precautions to prevent damage. To prevent electrostatic damage, observe the following precautions:

■Transport products in static-safe containers such as conductive tubes, bags, or boxes.

■Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.

■Cover workstations with approved static-dissipating material. Provide a wrist strap connected to the work surface and properly grounded (earthed) tools and equipment.

■Keep work area free of nonconductive materials, such as ordinary plastic assembly aids and foam packing.

■Make sure you are always properly grounded (earthed) when touching a static-sensitive component or assembly.

■Avoid touching pins, leads, or circuitry.

■Always place drives with the PCB-assembly-side down.

■Use conductive field service tools.

2-4 Compaq ProLiant ML350 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 can damage electronic components. Be sure you are properly grounded (earthed) before beginning any installation procedure. See “Electrostatic Discharge” earlier in this chapter for more information.

Before beginning any removal and replacement procedure for non-hot-plug devices:

1.Power down the ProLiant ML350 server and any peripheral devices.

2.Disconnect the AC power cord from the AC outlet, and then disconnect from the server.

3.Disconnect all external peripheral devices from the server.

NOTE: If you have installed a rack upgrade kit, you must remove the ProLiant ML350 server from the rack and place it on a sturdy table or workbench. Refer to the Compaq ProLiant ML350 Setup and Installation Guide for instructions.

Rack Warnings

WARNING: To reduce the risk of personal injury or damage to the equipment:

■Always load the heaviest item first, and load the rack from the bottom up. This step makes the rack “bottom-heavy” and helps prevent the rack from becoming unstable.

■The bottom stabilizers on the equipment must be fully extended. Be sure that the equipment is properly supported/braced when installing options and cards.

■Extend only one component at a time. A rack may become unstable if more than one component is extended for any reason. Be sure that the rack is adequately stabilized before extending a component outside the rack.

■Before beginning work on the rack, be sure that the leveling jacks are extended to the floor, that the full weight of the rack rests on the level floor, and that either stabilizers are installed or multiple racks are coupled for stability.

■Because the rack allows you to stack computer components on a vertical rather than horizontal plane, you must take precautions to provide for rack stability and safety and to protect both personnel and property. Heed all cautions and warnings in the installation instructions that come with the server.

■Tipping can cause injury or death.

WARNING: To reduce the risk of personal injury, fire, or damage to the equipment, do not overload the AC supply branch circuit that provides power to the rack.

Removal and Replacement Procedures 2-5

Server Warnings and Precautions

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 server must always be operated with system unit covers on. Proper cooling is not achieved if the system unit covers are removed.
