Preparing for installation

CAUTION:
The weight of this part or unit is more than 55 kg (121.2 lb). It takes specially trained persons, a
lifting device, or both to safely lift this part or unit. (C011)
CAUTION: The enclosure—together will all its component parts—is too heavy to manually lift and
install into the rack cabinet. A minimum of three people and a suitable mechanical lift are required
to hoist the enclosure and install it into the rail kit assembly within the rack.
Make sure you wear an effective anti-static wrist or ankle strap and obey conventional ESD precautions
when touching modules and components. Do not touch midplane, motherboard, or module connectors.
See also ESD precautions.
This section provides important preparation requirements and handling procedures for use during
