IBM Power System S822LC Installing The System And Ordered Parts page 9

v 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.
v 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.
v 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 2 of 2):
CAUTION:
v 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.
v 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.
v 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.
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.
