Hard disk drives
Hard disk drives are fragile, precision components. Avoid subjecting them to physical shock and
vibration. The following guidelines apply to all drives, including failed drives, replacement drives, and
spares.
●
Do not remove hard disk drives from the shipping package for storage. Keep hard disk drives in
their protective packaging until they are mounted in the workstation.
●
Avoid dropping hard disk drives from any height.
●
If you are inserting or removing a hard disk drive, power off the workstation. Do not remove a hard
disk drive while the workstation is powered on or in standby mode.
●
Before handling a drive, be sure that you discharge static electricity. While handling a drive, avoid
touching the connector. For more information about preventing electrostatic damage, see
ESD
information on page 62.
To prevent possible ESD damage when the drive is installed, connect the drive power cable before
connecting the data cable. This discharges accumulated static electricity through the drive power
cable to the workstation chassis.
●
When inserting a drive, do not use excessive force.
●
Avoid exposing a hard disk drive to liquids, temperature extremes, or products with magnetic fields
such as monitors or speakers.
Lithium coin cell battery
The battery included with the workstation provides power to the real-time clock and has a lifetime of
about three years.
For instructions on battery removal and replacement, see
Battery on page 108.
WARNING! This workstation contains a lithium battery. There is a risk of fire and chemical burn if the
battery is handled improperly. Do not disassemble, crush, puncture, short the external contacts, dispose
of in water or fire, or expose the battery to temperatures higher than 60° Centigrade (140° Fahrenheit).
NOTE: Do not dispose of batteries, battery packs, and accumulators with general household waste.
Customer self-repair
Under the Customer Self-Repair program, you can order a replacement part and install the part without
onsite HP technical assistance. See
http://www.hp.com/go/selfrepair/ for information on the program as
customer self-repair may be required for some components.
NOTE: Some components, like the liquid cooling system, are not eligible for Customer Self-Repair
and must be returned to HP for service. Call HP Support for further instructions before attempting to
