Warning
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
• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the
Step 1
Look at the fan and power supply modules installed in the chassis to determine how you must position the bottom-support
rails on the rack.
• If the fan modules have blue coloring (port-side exhaust modules), you must position the bottom support rails so
that the chassis stop is positioned by the cold aisle.
• If the fan modules have burgundy (port-side intake modules), you must position the bottom support rails so that the
chassis stop is positioned by the hot aisle.
Step 2
Separate the two sliders that make up one bottom-support rail and position the half with the chassis stop by the appropriate
aisle for the fan and power supply modules. Also make sure that there is at least 1 rack unit open above the bottom-support
rails so that you can easily install the chassis.
Step 3
Use two customer-supplied screws (typically M6 x 10 mm screws) to attach the bottom-support rail half to the vertical
mounting rails on the rack post. Tighten each screw to the appropriate torque setting for the screws (for M6 x 10 mm
screws, use 40 in. lbs [4.5 N·m] of torque).
Step 4
Slide the other half of the bottom-support rail onto the attached half of the rail set and use two customer supplied screws
(typically M6 x 10 mm screws) to secure that portion to the vertical mounting rails on the rack. Tighten each screw to
the appropriate torque setting for the screws (for M6 x 10 mm screws, use 40 in. lbs [4.5 N·m] of torque).
