Server Warnings and Precautions

IMPORTANT: The installation of options and servicing of this product shall be performed by individuals
who are knowledgeable of the procedures, precautions, and hazards associated with equipment
containing hazardous energy circuits.
WARNING: To reduce the risk of personal injury from electric shock and hazardous energy
levels, only authorized service technicians should attempt to repair this equipment. Improper
repairs could create conditions that are hazardous.
WARNING: To reduce the risk of personal injury from hazardous energy or damage to the
equipment when working on energized servers:
I Remove all watches, rings, and any other loose-fitting jewelry.
I Do not use conductive tools inside the server that could bridge live parts.
WARNING: To reduce the risk of electric shock or damage to the equipment:
I Do not disable the power cord grounding plug. The grounding plug is an important safety
feature.
I Plug the power cord into a grounded electrical outlet that is easily accessible at all times.
I Install the power supply before connecting the power cord to the power supply.
I Unplug the power cord before removing the power supply from the server.
I If the system has multiple power supplies, disconnect power from the system by
unplugging all power cords from the power supplies.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal system
components to cool before touching them.
CAUTION: Because the Compaq ProLiant 8500 server does not have safety interlocks, it is
possible for a unit to be operated without the cover and air baffles properly installed. This could
cause thermal damage in the system and may void your warranty. The rack-mountable
Compaq ProLiant 8500 server should always be operated with the system unit cover on. Proper
cooling will not be achieved if the system unit cover is removed for extended periods of time.
CAUTION: Protect the server from power fluctuations and temporary interruptions with a
regulating uninterruptible power supply (UPS). This device protects the hardware from damage
caused by power surges and voltage spikes and keeps the system in operation during a power
failure.
