Service Preparation
WARNING: To reduce the risk of personal injury from hot surfaces, allow the internal
system components to cool before touching them.
CAUTION: Because the HP ProLiant DL740 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 could void the warranty. The rack-mountable
HP ProLiant DL740 server should always be operated with the system unit cover on. Proper
cooling cannot 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.
