Fire suppression systems

A fire suppression system is the responsibility of the customer. The customer's own
insurance underwriter, local fire marshal, or a local building inspector, or both,
should be consulted in selecting a fire suppression system that provides the correct
level of coverage and protection. IBM designs and manufactures equipment to
internal and external standards that require certain environments for reliable
operation. Because IBM does not test any equipment for compatibility with fire
suppression systems, IBM does not make compatibility claims of any kind nor
does IBM provide recommendations on fire suppression systems.
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 32U 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 32U 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 when moving the rack 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 came with your rack cabinet
for the weight of a loaded rack cabinet.
– Verify that all door openings are at least 760 x 2030 mm (30 x 80 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
during movement.
– 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 bolt the rack cabinet to the
pallet.
