Step 7
If the ports require cleaning, open one or more port connector hinged
caps from the circuit packs.
Step 8
Blow off any accumulated dust or loose debris from the ferrules with
canned, oil-free compressed air.
Step 9
Clean the ports by using 1.25 mm cotton swabs.

Step 10 After cleaning and inspecting a port, close the cap immediately on
any port that you are not cabling, to prevent contamination of the con-
nector.
Step 11 If the connector is still dirty, repeat the dry cleaning technique.
Step 12 Inspect the connector again using the video scope. If the connector is
still dirty after a second dry cleaning, clean it with a wet cleaning tech-
nique, followed immediately with another dry cleaning, to ensure that
no residue is left on the endface.
To perform a wet cleaning, gently wipe the ferrules and endface sur-
faces of the connector plugs using a pad saturated with optical-grade
isopropyl alcohol. Make sure that the pad makes full contact with the
endface surfaces.
