Cleaning Bulkheads - Cisco GS7000 Installation And Operation Manual

Maintenance
b Listen for a slight "squeak" typically generated during this process, indicating a clean connector.
c Inspect the connector again through the scope to confirm that it is clean.
3 If a second inspection indicates that further cleaning is needed:
a Use 99% isopropyl alcohol and a lint-free wipe to clean the connector.
b Use the appropriate ferrule cleaner again to remove any film left over from the alcohol.
c Inspect the connector again through the scope and confirm that it is clean.
4 If necessary, repeat steps 3a-3c until the connector is clean.

Cleaning Bulkheads

It is generally more difficult to clean bulkhead connectors and verify their condition due to limited
Note
accessibility of the fiber end face. For this reason, even on products with accessible bulkhead connectors,
you should only attempt to clean a bulkhead connector when a dirty connector is indicated.
Follow these steps to clean the bulkhead:
Warning
• Avoid personal injury! Use of controls, adjustments, or performance of procedures other than those
specified herein may result in hazardous radiation exposure.
• Avoid personal injury! The laser light source on this equipment emits invisible laser radiation. Avoid
direct exposure to the laser light source.
• Avoid personal injury! Viewing the laser output with optical instruments (such as eye loupes,
magnifiers, or microscopes) may pose an eye hazard.
1 Insert a dry bulkhead swab into the bulkhead and rotate the swab several times.
2 Remove the swab and discard. Swabs may be used only once.
3 Check the bulkhead optical surface with a fiber connector scope to confirm that it is clean. If further
cleaning is needed:
a Moisten a new bulkhead swab using a lint-free wipe moistened with optical-grade (99%) isopropyl
alcohol.
b With the connector removed, fully insert the bulkhead swab into the bulkhead and rotate the swab
several times.
c Remove the swab and discard. Swabs may be used only once.
d Check with a fiber connector scope again to confirm that there is no dirt or alcohol residue on the
optical surface.
e If any alcohol residue remains, clean it off with a new dry bulkhead swab.
