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. (R001 part 1 of
