Installing the Chassis in a Four-Post Rack
You need to slide the chassis onto the bottom-support rails so that the power supply end locks onto the chassis
stops at the end of the rails and so that the front-mount brackets on the chassis come into contact with the
front-mount rails on the rack.
Statement 1074
—
Comply with Local and National Electrical Codes
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 four-post rack is properly installed and secured to the concrete subfloor.
• Make sure that the bottom support rails are installed so that the fan modules will be in the appropriate
aisle as follows:
◦ Burgundy (port-side intake airflow) fan modules are positioned in a hot aisle (the chassis stop on
the bottom-support rails is positioned by the hot aisle).
◦ Blue colored (port-side exhaust airflow) fan modules are positioned in a cold aisle (the chassis
stop on the bottom-support rails is positioned by the cold aisle).
Power supply modules must have the same airflow direction as the fan modules but
might have different coloring if they use DC power (green coloring for port-side intake
airflow). Note
• Make sure that two front-mount brackets are securely fastened to the sides of the chassis at the port end.
• Make sure that you have two customer-supplied rack-mount screws (M6 x 10 mm or appropriate screw
for the vertical mounting rails on the rack).
