Removal and Replacement Procedures

Electrostatic Discharge Information

An electrostatic discharge (ESD) 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. Use 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 that 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 Printed Circuit Board (PCB) assembly-side down.

• Use conductive field service tools.

Removal and Replacement Procedures

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. Refer to
“Electrostatic Discharge Information” earlier in this chapter for more information.

Before removing any serviceable parts, determine whether the part is hot-pluggable or
non-hot-pluggable.

Non-Hot-Pluggable Device

If the device is non-hot-pluggable, the server must be powered down. Non-hot-pluggable
devices in the server include the processor, all boards, memory modules, fans, and drive
cages.

Powering Down the Server

System power in the server does not completely power down when the front panel power
button is pressed. The button toggles between on and standby, rather than on and off. The
standby position removes power from most electronics and the drives, but some internal
circuitry remains active. To completely remove all power from the system, you must
disconnect all power cords from the server.

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

To power down the server:

1. Press the power button to toggle to standby. This places the server in standby mode,
thereby disabling the main power supply output and providing auxiliary power to the
server. Standby does not completely disable or remove power from the system.

COMPAQ CONFIDENTIAL Codename: Forge Part Number: 236634-002 Last Saved On: 5/14/02 12:00 PM

2. Be sure that the system LED closest to the right on the front panel is amber and that the

fan noise has stopped.

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

4. Disconnect all external peripheral devices from the server.

Rack Stability Warning

For stability and safety, properly positioning the server is critical.

WARNING: To reduce the risk of personal injury or damage to the equipment, be sure
that:

• The leveling jacks are extended to the floor.

• The full weight of the rack rests on the leveling jacks.

• The stabilizing feet are connected to the rack if it is a single-rack installation.

• The racks are coupled together in multiple-rack installations.

• Only one component is extended at a time. A rack may become unstable if more

than one component is extended for any reason.
