Rack safety notices

You need to read the rack safety notices before installing equipment.

About this task

Before installing a rack, rack features, or a system or expansion unit into a rack, read the following safety information.

Attention: If you are installing equipment into a non-IBM rack, the rack must comply with the Electronics Industries Association (EIA) 310D specifications. If you do not have a rail kit designed for the equipment in the non-IBM rack, do not install the equipment into the rack as damage to the equipment or personal injury could occur.
(R001 part 1 of 2):
DANGER
Observe the following precautions when working on or around your IT rack system:
  • Heavy equipment–personal injury or equipment damage might result if mishandled.
  • Always lower the leveling pads on the rack cabinet.
  • Always install stabilizer brackets on the rack cabinet if provided, unless the earthquake option is to be installed.
  • 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 shelves or work spaces. Do not place objects on top of rack-mounted devices. In addition, do not lean on rack mounted devices and do not use them to stabilize your body position (for example, when working from a ladder).

  • Stability hazard:
    • The rack may tip over causing serious personal injury.
    • Before extending the rack to the installation position, read the installation instructions.
    • Do not put any load on the slide-rail mounted equipment mounted in the installation position.
    • Do not leave the slide-rail mounted equipment in the installation position.
  • Each rack cabinet might have more than one power cord.
    • For AC powered racks, be sure to disconnect all power cords in the rack cabinet when directed to disconnect power during servicing.
    • For racks with a DC power distribution panel (PDP), turn off the circuit breaker that controls the power to the system unit(s), or disconnect the customer’s DC power source, when directed to disconnect power during servicing.
  • 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. (R001 part 1 of 2)
(R001 part 2 of 2):
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, front, or back of a unit used for air flow through 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 or if the rack is not bolted to the floor. Do not pull out more than one drawer at a time. The rack might become unstable if you pull out more than one drawer at a time.

  • (For fixed drawers.) This drawer is a fixed drawer and must not be moved for servicing unless specified by the manufacturer. Attempting to move the drawer partially or completely out of the rack might cause the rack to become unstable or cause the drawer to fall out of the rack. (R001 part 2 of 2)
