Removal and Replacement Procedures
WARNING: To reduce the risk of personal injury or damage to the equipment, at least
two people are needed to safely unload the rack from the pallet. An empty 42U rack
weighs 115 kg (253 lb), is over 2.1 m (7 ft) tall, and may become unstable when being
moved on its casters. Do not stand in front of the rack as it rolls down the ramp from
the pallet, but handle the rack from both sides.
WARNING: To reduce the risk of shock or injury from high-current electrical energy,
do not reach into a server blade enclosure once it has been installed in a rack and
connected to a working rack bus bar. Do not touch the power or data backplanes within
the server blade enclosure once it has been installed.
WARNING: To reduce the risk of shock or injury from high-current electrical energy,
do not reach into a power supply enclosure once it has been installed in a rack and
connected to a power source. Do not touch the connectors within the power supply
enclosure once it has been installed.
WARNING: To reduce the risk of shock or injury from high-current electrical energy,
do not open any access covers on the rack bus bar or power bus box after it has been
connected to a power source.
CAUTION: Always ensure that equipment is properly grounded before beginning any
installation procedure. Electrostatic discharge resulting from improper grounding can damage
electronic components. For more information, refer to the setup and installation guide.
