Installing Enclosures into the Rack

WARNING: Be sure that the power enclosure AC power cords are not
connected to a power source.
WARNING: To reduce the risk of personal injury and damage to the
equipment, always begin by mounting the heaviest item on the bottom of the
rack. Continue to populate the rack from the bottom to the top. Failure to do so
may make the rack unstable.
WARNING: Remove all hot-plug power supplies before loading a power
enclosure into the rack. Blanks can be left in the enclosure for installation.
WARNING: Remove all server blades before loading a server blade enclosure
into the rack. Blanks can be left in the enclosure for installation.
WARNING: At least two people must lift an enclosure into the rack together. If
the enclosure is loaded into the rack above chest level, a third person MUST
assist with aligning the enclosure with the rails while the other two people
support the weight of the enclosure.
WARNING: To reduce the risk of personal injury or damage to the equipment,
you must adequately support the power enclosure and the server blade
enclosure during installation and removal. They are not secured to the rack
frame.
To load a power enclosure or server blade enclosure into the rack:
1. Install the rack rails and cage nuts. Refer to the "Installing the Rack Rails and
Cage Nuts" section in this chapter.
IMPORTANT: You must install rack rails and cage nuts for each enclosure.
2. Position yourself at the front of the rack.
NOTE: Blanks can remain in the enclosures during installation because they do not add
significant weight to the component.
