(R001 part 1 of 2):
DANGER: Observe the following precautions when working on or around your IT rack system:
vHeavy equipment–personal injury or equipment damage might result if mishandled.
vAlways lower the leveling pads on the rack cabinet.
vAlways install stabilizer brackets on the rack cabinet.
vTo 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.
vRack-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).
vi Power Systems: Servicing the IBM Power System LC921 (9006-12C)

vEach 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.
vConnect 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.
vAn 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 2 of 2):
CAUTION:
vDo 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.
vDo 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.
vConsideration 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.
v(For sliding drawers.) Do not pull out or install any drawer or feature if the rack stabilizer brackets are
not attached to the rack. 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.
v(For fixed drawers.) This drawer is a fixed drawer and must not be moved for servicing unless specified
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.
Safety notices vii

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.
vReduce 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 observe the following precautions:
– 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 configuration specifically allowed it.
vIf the rack cabinet you are relocating is part of a suite of rack cabinets, detach the rack cabinet from
the suite.
vIf the rack cabinet you are relocating was supplied with removable outriggers they must be
reinstalled before the cabinet is relocated.
vInspect the route that you plan to take to eliminate potential hazards.
vVerify 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.
vVerify that all door openings are at least 760 x 230 mm (30 x 80 in.).
vEnsure that all devices, shelves, drawers, doors, and cables are secure.
vEnsure that the four leveling pads are raised to their highest position.
vEnsure that there is no stabilizer bracket installed on the rack cabinet during movement.
vDo not use a ramp inclined at more than 10 degrees.
vWhen the rack cabinet is in the new location, complete the following steps:
– 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.
vIf a long-distance relocation is required, restore the rack cabinet to the configuration of the rack
