(R001 part 1 of 2):

DANGER: Observe the following precautions when working on or around your IT rack system:

• Heavy equipment–personal injury or equipment damage might result if mishandled.

• Always lower the leveling pads on the rack cabinet.

• Always install stabilizer brackets on the rack cabinet unless the earthquake option is to be

installed.

• To avoid hazardous conditions due to uneven mechanical loading, always install the heaviest

devices in the bottom of the rack cabinet. Always install servers and optional devices starting

from the bottom of the rack cabinet.

vi Power Systems: System backplane

• Rack-mounted devices are not to be used as shelves or work spaces. Do not place objects on top

of rack-mounted devices. In addition, do not lean on rack mounted devices and do not use them

to stabilize your body position (for example, when working from a ladder).

• Each rack cabinet might have more than one power cord.

– For AC powered racks, be sure to disconnect all power cords in the rack cabinet when directed

to disconnect power during servicing.

– For racks with a DC power distribution panel (PDP), turn off the circuit breaker that controls

the power to the system unit(s), or disconnect the customer’s DC power source, when

directed to disconnect power during servicing.

• 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.

• An electrical outlet that is not correctly wired could place hazardous voltage on the metal parts

of the system or the devices that attach to the system. It is the responsibility of the customer to

ensure that the outlet is correctly wired and grounded to prevent an electrical shock. (R001 part

1 of 2)

(R001 part 2 of 2):

CAUTION:

• Do not install a unit in a rack where the internal rack ambient temperatures will exceed the

manufacturer's recommended ambient temperature for all your rack-mounted devices.

• Do not install a unit in a rack where the air flow is compromised. Ensure that air flow is not

blocked or reduced on any side, front, or back of a unit used for air flow through the unit.

• Consideration should be given to the connection of the equipment to the supply circuit so that

overloading of the circuits does not compromise the supply wiring or overcurrent protection. To

provide the correct power connection to a rack, refer to the rating labels located on the

equipment in the rack to determine the total power requirement of the supply circuit.

•(For sliding drawers.) Do not pull out or install any drawer or feature if the rack stabilizer

brackets are not attached to the rack or if the rack is not bolted to the floor. Do not pull out more

than one drawer at a time. The rack might become unstable if you pull out more than one drawer

at a time.

•(For xed drawers.) This drawer is a xed drawer and must not be moved for servicing unless

specied by the manufacturer. Attempting to move the drawer partially or completely out of the

rack might cause the rack to become unstable or cause the drawer to fall out of the rack. (R001

part 2 of 2)

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 conguration of the rack cabinet as you

received it. If this conguration is not known, you must observe the following precautions:

Safety notices vii

– Remove all devices in the 32U position (compliance ID RACK-001 or 22U (compliance ID

RR001) and above.

– Ensure that the heaviest devices are installed in the bottom of the rack cabinet.

– Ensure that there are little-to-no empty U-levels between devices installed in the rack cabinet

below the 32U (compliance ID RACK-001 or 22U (compliance ID RR001) level, unless the

received conguration specically allowed it.

• If the rack cabinet you are relocating is part of a suite of rack cabinets, detach the rack cabinet

from the suite.

• If the rack cabinet you are relocating was supplied with removable outriggers they must be

reinstalled before the cabinet is relocated.

• 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 230 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 10 degrees.

• When the rack cabinet is in the new location, complete the following steps:

– Lower the four leveling pads.

– Install stabilizer brackets on the rack cabinet or in an earthquake environment bolt the rack to

the floor.

– 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 conguration 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.
