Removal and Replacement Procedures

This chapter provides subassembly/module-level removal and replacement procedures for Compaq ProLiant 8000 servers. After completing all necessary removal and replacement procedures, run the Diagnostics program to verify that all components operate properly.

To service Compaq ProLiant 8000 servers, you might need the following:

■ Flatblade screwdriver

■ Phillips screwdriver

■ Torx T-15 screwdriver

■ From the Compaq SmartStart and Support Software CD:

 System Configuration Utility software

 Drive Array Advanced Diagnostics software

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 tools and equipment.

■ Keep the work area free of nonconductive materials, such as plastic assembly aids and

foam packing.

■ Make sure you are always properly grounded when touching a static-sensitive component

or assembly.

■ Avoid touching pins, leads, or circuitry.

■ Always place drives PCB assembly-side down.

■ Use conductive field service tools.

Symbols in Equipment

WARNING: Any surface or area of the equipment marked with these symbols

indicates the presence of a hot surface or hot component. If this surface is contacted, the potential for injury exists. To reduce the risk of

injury from a hot component, allow the surface to cool before touching it.

WARNING: Any surface or area of the equipment marked with these symbols indicates the presence of electric shock hazards. The enclosed area contains no operator-serviceable parts. To reduce the risk of injury from electric shock, do not open this enclosure.

WARNING: Any product or assembly marked with these symbols indicates that the

weight in kg

weight in lb

component exceeds the recommended weight for one individual to handle safely. To reduce the risk of personal injury or damage to the equipment, observe local occupational health and safety requirements and guidelines for manual material handling.

WARNING: Any RJ-45 receptacle marked with these symbols indicates a Network Interface Connection. To reduce the risk of electric shock, fire, or damage to the equipment, do not plug telephone or telecommunications connectors into this receptacle.

CLASS 1 LASER PRODUCT

WARNING: This label or equivalent is located on the surface of your CD-ROM drive. This label indicates that the product is classified as a CLASS 1 LASER PRODUCT.

WARNING: To reduce the risk of injury from electric shock, remove all power cords to completely disconnect power from the system. Power supplies marked with these symbols indicate the equipment is supplied by multiple sources of power.

System Interlocks

Compaq ProLiant 8000 servers ship with system interlocks. System interlocks consist of three LEDs providing a closed-loop checking mechanism for verifying proper cabling interconnects between critical server components. These LEDs are located on both the I/O and the processor boards. They provide a visual aid to assist in isolating components to check if the server will not power up because of a broken interlock chain. The I/O board is located directly beneath the PCI Hot Plug access doors under the top access panel. An amber system power LED on the front of the server will illuminate whenever the interlock chain is broken.

Preparation Procedures

Hot-Pluggable Parts

Before beginning the removal of any serviceable parts, determine whether the part is hot-pluggable or non-hot-pluggable. If it is hot-pluggable, do not perform a power shutdown of the server. The access panels can be removed while the server is powered up without causing a system shutdown. When the server is in Standby mode, portions of the power supply, auxiliary power (+5V), and some internal circuitry will remain active.

Removal and Replacement Procedures 2-3

Non-Hot-Pluggable Parts

If any serviceable parts are non-hot-pluggable, then the server must be shut down. Non-hot-pluggable parts include the processor, Processor Power Module, system board, memory board, and DIMMs. Refer to “Turning Off the Server” later in this chapter for complete instructions.

2-4 Compaq ProLiant 8000 Intel Pentium III Xeon 700MHz Servers Maintenance and Service Guide

Turning Off the Server

The ProLiant 8000 server’s Power On/Standby switch does not shut off the system power completely. The switch functions as On and Standby, rather than On and Off. Standby mode removes power from most of the electronics and the drives, but portions of the power supply and some internal circuitry remain active.

IMPORTANT: To completely remove all power from the system, you must disconnect the power cord from the server. In systems with multiple power supplies, you must disconnect all power cords to completely remove power from the system.

IMPORTANT: It is not necessary to turn off the server to replace hot-plug devices, such as PCI Hot Plug power supplies or hot-plug fans.

NOTE: It is necessary to be knowledgeable of electrostatic discharge information before performing the preparation procedures. For electrostatic discharge information, see “Electrostatic Discharge Information” earlier in this chapter.

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

1. Press the Power On/Standby switch to Standby mode. This disables the main power

supply output and provides auxiliary power (+5V) to the server. Standby does not disable main AC power.

2. Verify that the system LED on the front panel, near the Power On/Standby switch, is off

and that the fan noise abates.

3. Disconnect all power cords from the server.

4. For some removal and replacement procedures, you must remove the server from the rack

and place it on a sturdy table or workbench. Refer to the Compaq ProLiant 8000 Setup and Installation Guide for instructions.

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

46 – 109 kg

100 – 240 lb

WARNING: 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. These precautions also protect both personnel and property. Follow all cautions and warnings throughout the installation instructions that came with the server.

■ Observe local Occupational Safety requirements and guidelines for heavy

equipment handling.

■ Obtain adequate assistance to lift and stabilize the product during installation or
