Rack installation

DANGER
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 cabinets.
v Rack-mounted devices are not to be used as a shelf or work
space. Do not place any object 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 before
servicing any device in the rack cabinet.
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.
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.
v 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 may
become unstable if you pull out more than one drawer at a time.
v (For fixed drawers.) This drawer is a fixed drawer and should not
be moved for servicing unless specified by manufacturer.
Attempting to move the drawer partially or completely out of the
rack may cause the rack to become unstable or cause the drawer
to fall out of the rack.
