Serviceability features
The computer includes features that make it easy to upgrade and service. No tools are needed for most of
the installation procedures described in this chapter.
Warnings and cautions
Before performing upgrades be sure to carefully read all of the applicable instructions, cautions, and
warnings in this guide.
WARNING! To reduce the risk of personal injury from electrical shock, hot surfaces, or fire:
Disconnect the power cord from the wall outlet and allow the internal system components to cool before
touching.
Do not plug telecommunications or telephone connectors into the network interface controller (NIC)
receptacles.
Do not disable the power cord grounding plug. The grounding plug is an important safety feature.
Plug the power cord in a grounded (earthed) outlet that is easily accessible at all times.
To reduce the risk of serious injury, read the Safety & Comfort Guide. It describes proper workstation, setup,
posture, and health and work habits for computer users, and provides important electrical and mechanical
safety information. This guide is located on the Web at http://www.hp.com/ergo.
WARNING! Energized and moving parts inside.
Disconnect power to the equipment before removing the enclosure.
Replace and secure the enclosure before re-energizing the equipment.
CAUTION: Static electricity can damage the electrical components of the computer or optional equipment.
Before beginning these procedures, ensure that you are discharged of static electricity by briefly touching a
grounded metal object. See Electrostatic discharge on page 26 for more information.
When the computer is plugged into an AC power source, voltage is always applied to the system board. You
must disconnect the power cord from the power source before opening the computer to prevent damage to
internal components.
