Rack safety
Rack installation
DANGER
Observe the following precautions when working on or around your IT rack system:
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
Rack-mounted devices are not to be used as shelves or work spaces. Do not
place objects on top of rack-mounted devices.
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.

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.
