Converting The System From Tower Mode To

Rack Mode

CAUTION: Many repairs may only be done by a certified service technician. You should only perform

troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or

telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your

warranty. Read and follow the safety instructions that came with the product.

CAUTION: Do not attempt to convert your system into a rack unless authorized by Dell. Only customers certified by

Dell for tower to rack conversion can convert a tower system into a rack system.

Safety Instructions

NOTE: For specific caution statements and procedures, see the rack installation documentation for your system at

support.dell.com/manuals. For complete safety and regulatory information, see the safety instructions that shipped

with your system.

Observe the following precautions for stability and safety of the system in rack mode:

• Before installing your equipment in a rack, install the front and side rack stabilizers. Failure to install stabilizers

can allow the rack to tip over.

• Always load from the bottom up, and load the heaviest items first.

• Do not overload the AC power supply branch circuit that provides power to the rack.

• Do not stand or step on any components in the rack.

Preparing A System For Conversion From Tower Mode To Rack

Mode

You require the tower to rack conversion kit, which contains the following items:

• Rack ears (left and right) with three screws each

• VGA module

• Control panel for rack mode

• LCD panel

• Rack slide cover

• Mylar cover

• If applicable, a pair of rails

1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet and

peripherals.

2. If applicable, rotate the system feet inward and lay the system on its side on a flat, stable surface.

NOTE: For systems installed with the wheel assembly, ensure that you lay the system on a sturdy, stable

surface.
