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 or equipment damage from electric shock, hot surfaces, or fire:
Energized and moving parts are inside. Disconnect power to the equipment before removing the enclosure.
Allow the internal system components to cool before you touch them.
Replace and secure the enclosure before re-energizing the equipment.
Do not plug telecommunications or telephone connectors into the network interface controller (NIC) receptacles.
Do not disable the AC power cord grounding plug. The grounding plug is an important safety feature.
Plug the AC power cord into a grounded (earthed) AC 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 and
provides guidelines for posture and work habits that increase your comfort and decrease your risk of injury. It
also provides electrical and mechanical safety information. This guide is located on the web at

CAUTION: Static electricity can damage the electrical components of the thin client or optional equipment.
Before beginning the following procedures, be sure that you are discharged of static electricity by briefly
touching a grounded metal object.
When the thin client 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 thin client to prevent damage to internal
components.
