Rack Safety
The following general safety information should be used for all rack mounted
devices.

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 cabinet.

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. Ensure that all

power cords in the rack cabinet are disconnected 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.

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 of the unit.

v Connect the equipment to the supply circuit such 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 may become unstable if you pull out more than
one drawer at a time.

v (For fixed drawers) Do not move a fixed drawer. 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.
