1Getting Started
The following important information must be adhered to for proper removal and
replacement of all Hewlett-Packard parts.
Safety Warnings
WARNING Removing the device cover may expose sharp edges in the equipment
chassis. To avoid injury, use care when installing customer add-on
devices.
NOTE Before performing removal/replacement procedures, position the workstation
on a cushioned flat, stable surface, such as a table top or workbench.
NOTE Installing the recommended HP replacement part in your B Class and C
Class workstation does not affect the regulatory and safety classifications or
approvals listed in the original owner’s guide.
Electrostatic Discharge (ESD) Precautions
To prevent damage to the B Class and C Class workstation, observe all of the following
ESD precautions while performing removal and replacement procedures:
• Remove all ESD-generating materials from the work area in which you will remove and
replace the workstation field replaceable unit(s).
• Open the ESD materials provided with the replacement part kit. Unfold the black
conductive sheeting (antistatic mat) and place it under a corner of the workstation.
• Wear a static strap to ensure that any accumulated electrostatic charge is discharged
from your body to ground. Attach the static-grounding wrist strap by following the
instructions on the package. Attach the sticky end of the wrist strap to bare metal on
the rear panel of the workstation.
• Connect all equipment together, including the static-free mat, static strap, clips
attached to the wrist strap, nodes, and peripheral units.
• Keep uninstalled printed circuit boards in their protective antistatic bags.
• Once you have removed printed circuit boards from their protective antistatic bags,
handle the printed circuit boards by their edges only.

Safely Powering Down the B Class and C Class Workstation
You must complete the following steps before performing any of the removal and
replacement procedures:
NOTE Remove any accessory bag(s) and their black tab screws, if present, from the
rear of the workstation.
1. Shut down the workstation by executing “shutdown -h” as user root. This ensures
that all programs are terminated and all data is saved before switching the power off.
Power down the workstation by simply pressing the power switch on the front panel.
Power off the monitor and any attached peripheral devices.
2. After 30 seconds, unplug the workstation’s power cord and all peripheral devices from
AC power outlets. Before attempting to move the workstation to a disassembly area,
disconnect all peripherals from the back of the system.
3. Place the workstation on a flat, stable surface, such as a tabletop or floor. To protect
against scratches, remove miscellaneous debris from the work surface.
