Information About Cleaning the OIM HBMT Connectors

This chapter describes how to clean the OIM HBMT connectors. In the fabric card chassis (FCC), the S2 and OIMs connect to each other using HBMT connectors located on the back of each card. Use the OIM HBMT adapter (see Figure 5-1) to clean these connectors.

How to Clean the OIM HBMT Connectors

Each OIM HBMT connector contains four optical ferrules. To access all ferrules, you must clean two ferrules and then rotate the adapter 180 degrees to clean the remaining two 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 OIM HBMT 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 OIM HBMT adapter into an OIM HBMT connector. Verify that the connector shutters open fully when you insert the adapter (see Figure 5-3).

Step 3 Insert the cleaning tool into the first adapter slot, as shown in Figure 5-4. 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 first two ferrules and then rotate the adapter to clean the remaining two ferrules.

Step 6 Repeat these steps for all OIM HBMT connectors that require cleaning.
