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 2)
