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 cabinets.
vRack-mounted devices are not to be used as ashelf or work
space. Do not place any object on top of rack-mounted
devices.
vEach 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.
vConnect all devices installed in arack cabinet to power
devices installed in the same rack cabinet. Do not plug a
power cord from adevice installed in one rack cabinet into a
power device installed in adifferent rack cabinet.
CAUTION:
vDo not install aunit in arack where the internal rack ambient
temperatures will exceed the manufacturer’s recommended
ambient temperature for all your rack-mounted devices.
vDo not install aunit in arack where the air flow is compromised.
Ensure that air flow is not blocked or reduced on any side, front,
or back of aunit 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.
vTo provide the correct power connection to arack, refer to the
