IBM NetBAY Rack: Planning Guide
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.
• Ensure that there is no stabilizer bracket installed on the rack cabinet.
• Do not use a ramp inclined at more than ten degrees.
• Once the rack cabinet is in the new location, do the following:
— Lower the four leveling pads.
— Install stabilizer brackets on the rack cabinet.
— If you removed any devices from the rack cabinet, repopulate the rack
cabinet from the lowest position to the highest position.
If a long distance relocation is required, restore the rack cabinet to the
configuration of the rack cabinet as you received it. Pack the rack cabinet in the
original packaging material, or equivalent. Also, lower the leveling pads to raise
the casters off of the pallet and strap the rack cabinet to the pallet.
