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.

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.
