Situation:
Further design review has suggested the addition of a clamping mechanism to ensure that the 8121-0118 ribbon
cable can not vibrate loose from the Test Set Motherboard connector during extreme handling.
New clamps and locking screws are being added to ensure that those printed circuit assemblies can not vibrate
loose from their connectors during extreme handling.
Solution/Action:
Enhancement No.1 (Applies to all Options)
1. Required Tool for Ribbon Cable Clamp
a. Gather a standard 10 lb-in breakaway wrench (used for semi-rigid cables).
b. Remove the open end head by loosening set screw. It will be replaced with L-Key shown below.
c. Secure and orient the L-Key to the breakaway handle
2. Ribbon Cable Clamp Installation Instructions
a. Remove and discard existing screw near ribbon cable connector on System Motherboard. See
below.

b. Insert Ribbon Cable Clamp under Source Assembly as shown.

Page 4 of 10 E8364B-07A
c. Position the clamp over the Ribbon Connector. Use needle nose pliers if necessary to slide the
clamp into place. Ensure that the edge of the clamp is parallel to the connector and not skewed.
NOTE: Ensure that the Clamp Lip is secured BELOW the edge of the System Motherboard

The Clip Retainer (E8361-20067) to be secured with Flat Head screw (0515-1644) in 2 places at 9 lb-in. This
Retainer Clip may naturally rotate a bit when being secured, which is acceptable. Note that the existing screw needs
to be removed and discarded prior installing Retainer Clip #1 (shown below in Figure 2a, 2b, and 3).
