DANGER
•
Plug power cords from devices in the rack cabinet into electrical outlets that are
located near the rack cabinet and are easily accessible.
•
Each rack cabinet might have more than one power cord. Be sure to disconnect all
power cords in the rack cabinet before servicing any device in the rack cabinet.
•
Install an emergency-power-off switch if more than one power device (power
distribution unit or uninterruptible power supply) is installed in the same rack
cabinet.
•
Connect all devices installed in a rack cabinet to power devices installed in the same rack
cabinet. Do not plug a power cord from a device installed in one rack cabinet into a power
device installed in a different rack cabinet.
Statement 11:
CAUTION:
Removing components from the upper positions in the rack cabinet improves rack stability during
relocation. Follow these general guidelines whenever you relocate a populated rack cabinet within a
room or building:
•
Reduce the weight of the rack cabinet by removing equipment starting at the top of the rack
cabinet. When possible, restore the rack cabinet to the configuration of the rack cabinet as you
received it. If this configuration is not known, you must do the following:
-
Remove all devices in the 22U position and above.
-
Ensure that the heaviest devices are installed in the bottom of the rack cabinet.
-
Ensure that there are no empty U-levels between devices installed in the rack cabinet
below the 22U level.
•
If the rack cabinet you are relocating is part of a suite of rack cabinets, detach the rack cabinet
from the suite.
•
Inspect the route that you plan to take to eliminate potential hazards.
•
Verify that the route that you choose can support the weight of the loaded rack cabinet. Refer to
the documentation that comes with your rack cabinet for the weight of a loaded rack cabinet.
•
Verify that all door openings are at least 760 x 2083 mm (30 x 82 in.)
•
Ensure that all devices, shelves, drawers, doors, and cables are secure.
•
Ensure that the four leveling pads are raised to their highest position.
