Safety Information
Follow the procedures listed below to ensure safe handling of components and to prevent
harm to both you and the server:
•
•
•
Use an anti-static wrist strap and a grounding mat.
Handle accessory boards and components by the edges only. Do not touch any metal-
edge connectors or any electrical components on accessory boards.
Do not wear clothing subject to static charge build-up, such as wool or synthetic
materials.
WARNING: Hazardous voltages are present inside the server. Always remove AC
power from the system and other associated assemblies while working inside the unit.
Serious injury may result if this warning is not observed.
WARNING: Before opening the HP server, always disconnect the power cords and
unplug telephone cables. Disconnect the power cords to avoid exposure to high
energy levels that may cause burns when parts are short-circuited by metal objects,
such as tools or jewelry. Disconnect telephone cables to avoid exposure to shock
hazard from telephone ringing voltages.
Note that the power switch does not turn off the standby power. Disconnect the power
cord to turn off standby power.
