v Heavy equipment–personal injury or equipment damage might result if mishandled.
v Always lower the leveling pads on the rack cabinet.
v Always install stabilizer brackets on the rack cabinet.
v 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.

v Each rack cabinet might have more than one power cord. Be sure to disconnect all
power cords in the rack cabinet 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 1 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. (R001 part 2 of 2)
