5. Route the cables within the tray as shown in

Figure 17

for entry from both sides or as

shown in

Figure 18

for entry from either left or right side. (Left side entry is shown.

Routing for right side entry is a mirror image of the routing shown.) All cable are
terminated on the front of the micro-VAMs.

Figure 17. Cable Routing for 72-Position Micro-VAM Tray (Enter From Both Sides)

Note: The sliding radius limiters must be in the position shown.

Note: Before tying off the cable as shown, proceed with the next step below.

Danger: Infrared radiation is invisible and can seriously damage the retina of the eye. Do not
look into the ends of any optical fiber. Do not look directly into the optical adapters of the adapter
packs. Exposure to invisible laser radiation may result. An optical power meter should be used to
verify active fibers. A protective cap or hood MUST be immediately placed over any radiating
adapter or optical fiber connector to avoid the potential of dangerous amounts of radiation
exposure. This practice also prevents dirt particles from entering the adapter or connector.
