a FIM
To install a FIM in a DSU Node:
WARNING: Fiber optic sources emit infrared light invisible to the human eye which can
damage the retina. Never look directly into a source or into the end of a fiber energized
by a source. When working with raw fiber optic cable, be careful of fiber ends or slivers
that can puncture the skin and cause irritation.
1. Attach the anti-static strap to your wrist.
2. Unpack the FIM. Inspect the FIM to ensure that it is not damaged.
3. Remove the DSU node front door
- Pry open the two latches on the right hand side of the black cover panel on the front
door, and swing the cover panel off to the left.
- Loosen the two screws under the black panel to release the front door.
- Pull the top corners of the front door out and lift it off the lip at the bottom front of the node.
4. Remove the DSU cards from the cabinet. Insert each circuit card in a separate anti-static
bag.
