Power supply modules must have the same airflow direction as the fan modules. HVAC/HVDC power supplies
with white coloring use the same direction of airflow as used by the fan modules.
Note
Statement 1074—Comply with Local and National Electrical Codes
To reduce risk of electric shock or fire, installation of the equipment must comply with local and national
electrical codes.
Warning
Statement 1032—Lifting the Chassis
To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles
on modules (such as power supplies, fans, or cards); these types of handles are not designed to support the
weight of the unit.
Warning
Before you begin
• Make sure that the two-post rack is properly installed and secured to the concrete subfloor.
• Make sure that two center-mount brackets are securely fastened to the middle of each side of the chassis.
• Make sure that you have six customer-supplied rack-mount screws (typically M6 x 10 mm or the
appropriate screw for the vertical mounting rails on the rack).
• You have at least two people to install the chassis.
Statement 1006—Chassis Warning for Rack-Mounting and Servicing
To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to
ensure that the system remains stable. The following guidelines are provided to ensure your safety:
• This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
• When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the
heaviest component at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the
unit in the rack.
Warning
Step 1 Use one person to position the chassis so that it is near the top of the rack with the fan and power supply modules in the
appropriate aisle and the center-mount bracket has its screw holes aligned to screw holes on the two-post rack.
If these modules have a blue coloring for port-side exhaust airflow, then you must position the modules by the cold aisle.
If the modules have a burgundy coloring for port-side intake airflow, you must position the modules by the hot aisle.
