Cleaning the Bulkhead Array Connectors

This chapter provides instructions for cleaning the optical array connectors located on the S13 cards in the line card chassis (LCC) to the optical interface modules (OIMs) in the fabric card chassis.

Information About Cleaning the Bulkead Array Connectors

This chapter describes how to clean the S13 array connectors. The bulkhead array connectors are located on the S13 fabric cards in the LCC and on the OIMs in the FCC. Use the OIM/S13 array adapter (see Figure 3-1) to clean these connectors. This adapter is the same one used to clean the optical array cables.

How to Clean the Bulkhead Array Connectors

Each bulkhead array connector contains six optical ferrules. To access all ferrules, you must clean three ferrules and then rotate the adapter 180 degrees to clean the remaining three ferrules.

Warning Because invisible radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid exposure to radiation and do not stare into open apertures. Statement 125

Warning Class 1M laser radiation when open. Do not view directly with optical instruments. Statement 281

Caution Before you begin, review the "General Reminders and Warnings" section.

To clean the bulkhead array connectors, follow these steps:

Step 1 Attach an ESD-preventive wrist strap to your wrist and connect its leash to an ESD connection socket or a bare metal surface on the chassis.

Step 2 Insert the array adapter into an array connector. Verify that the connector shutters open fully when you insert the adapter (see Figure 3-3).

Step 3 Insert the cleaning tool into the first adapter slot, as shown in Figure 3-4. Align the key on the cleaning tool with the matching notch in the adapter slot. The cleaning tool works only when the cleaning head is properly inserted.

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.
