Disclosed is a support mechanism for the free end of a Cable Management Arm (CMA) in a rack mounted computer system. The stabilization system suspends the end of a CMA from a stabilizing member that is attached to a stable location in order to prevent damage to the CMA while in service position.

Cable Mangement Arm (CMA) Stabilization Member

Cable Management Arms (CMAs), while in service position are vulnerable to damage. The damage may be caused by accidental user impact and/or fatigue caused by cable

weight. It is critical that the CMA remains intact during service.

Many existing solutions address overall CMA strength, but few address the concern of stability in the service position.

The proposed solution is a stabilizing member (SM) that connects the free end of the CMA to a stable point outside the CMA. While servicing a unit, the user opens the CMA into the service position and engages the SM. After use, the user disengages the SM, which retracts into a storage position in the CMA. The CMA can then be returned to a closed position. This device is novel because it provides a simple method of adding strength to a vulnerable feature. It can be easily integrated into a wide variety of CMAs and frames.

To implement the SM on a CMA:

1. The member provides an upward force on the free end of the CMA and is anchored to an independent stabile location (e.g., the frame)

2. The SM has a variable length allowing the use of multiple anchor points

3. When not in use, the SM retracts into compact storage within the CMA

4. The SM is spring-loaded and naturally retracts into the storage position

5. The locking mechanism that fixes...
