Safety precautions
Equipment handling guidelines
External power equipment, such as an uninterruptible power supply (UPS),
is usually very heavy. This equipment requires special handling procedures
and additional personnel for unloading and installation. Be aware of weight
distribution, and prevent the equipment room floor from being overly
stressed.
Safety information
In DC systems, locate the service panel near the entry to the room
containing the DC power system that supplies the server.
DANGER
Procedures involving electrical connections must be performed
only by qualified personnel.
Ensure that you obey all displayed warning notices on power
equipment and connections.
