Rack Safety
The following general safety information should be used for all rack mounted
devices.
DANGER
CAUTION:
• 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.
• 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.
• 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.
• (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.
• (For fixed drawers) This drawer is a fixed drawer and should not be moved for
servicing unless specified by the 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.
(R001)
• Always lower the leveling pads on the rack cabinet.
• Always install stabilizer brackets on the rack cabinet.
• 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.
• 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.
• 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.
• 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.
• 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.
