4.12:  Replacing the OC-3 Optical Channel (HC1A

and MC6A) Units

Issue 9, May 1999

FNC  and FNC Customer Use Only

Vol. ll, Page 480.4-52

Maintenance and Trouble Clearing
FJTU-320-515-480

4.12.2

Procedure—Removing the Optical Unit

Step 1

Using both hands, squeeze the lever lock tabs toward the levers and rotate the top 
and bottom extractor levers. Slide the unit out until the secondary latch engages 
(a little less than half way out of the slot). 

Step 2

Disconnect the optical fibers. Refer to Section 5.1, Handling Fiber Cables.

Step 3

If needed, install necessary optical connector cover on the fiber jumper. 

Step 4

Lift the metal spring of the secondary latch and pull the unit out.

Step 5

Are there more optical channel units (HC1A and MC6A) to be removed from the 
shelf?

   

If Yes:

If No:

Repeat procedure from Step 1 of 
Removing the Optical Channel Unit.

You have completed this procedure.
