Chapter 3 Cleaning the Bulkhead Array Connectors
How to Clean the Bulkhead Array Connectors
Step 4 Advance the thumb wheel until you hear two hard clicks. This advancement ensures that enough lint-free
cleaning cloth advances across the face of the fibers in the ferrule.
Note The thumb wheel makes a series of soft clicks followed by a “hard click” when turned. The hard click
is represented by six large notches along the edge of the thumb wheel. Always advance the thumb wheel
until you hear two hard clicks.
Step 5 Clean the three visible ferrules and then rotate the array adapter 180 degrees to clean the remaining three
ferrules.
Step 6 Repeat these steps for all bulkhead array connectors that require cleaning. The bulkhead array
connectors are located in the S13 and OIMs, as shown in
Figure 3-2.
