Strain-relieving the Cable Strength Member
Step 1:
Install the U-shaped washer and the flat washer on the strain-relief bracket using the
supplied Phillips-head machine screw (Figure 6).
Step 2:
Place the yarn, if present, and the central member between the U-shaped washer and the
flat washer.
Step 3:
Wrap yarn around the screw in a clockwise direction and under the U-shaped washer.
Step 4:
Tighten the nut.
Step 5:
Trim off the excess yarn and central member.
3.7
Grounding Armored Cable
•
One grounding kit (p/n FDC-CABLE-GRND, purchased separately) is required to ground each
armored cable. Follow instructions provided with the grounding kit.
•
Attach the other end of the ground wire to the equipment rack. The equipment rack must be
grounded to the primary building ground.
•
Remove the paint from the frame at the grounding location to ensure metal-to-metal contact. It is
recommended to use an antioxidant on the bare metal to prevent corrosion.
•
Or, attach the other end of the ground wire to a rack-mounted grounding bus bar, which is
grounded to the primary building ground.
3.8
Installing Preconnectorized Cable into Connector Panels
WARNING:
Never look directly into the end of a fiber that may be carrying
laser light.
Laser light is invisible and can damage your eyes. Viewing it directly
does not cause pain. The iris of the eye will not close involuntarily as when
viewing a bright light. Consequently, serious damage to the retina of the eye is
possible. Should accidental eye exposure to laser light be suspected, arrange for
an eye examination immediately.
WARNING:
DO NOT use magnifiers in the presence of laser radiation. Diffused
laser light can cause eye damage if focused with optical instruments. Should
accidental eye exposure to laser light be suspected, arrange for an eye
examination immediately.
CAUTION:
Isopropyl alcohol is flammable with a flashpoint at 54°F. It can cause
irritation to eyes on contact. In case of eye contact, flush eyes with water for at
least 15 minutes. Inhaling fumes may cause mild dizziness. In case of ingestion,
consult a physician.
Step 1:
Remove the blank panels from the unit and replace with connector panels (purchased
separately).
Step 2:
Install connectors into the adapters at the rear of the connector panels (Figure 7).
Step 3:
Route cable slack around radius control guides.
IMPORTANT:
Lift the tray stop latches and slide the drawer to the forward and back positions to
verify that the drawer slides in the grooves of the guides and that there is enough
fiber slack to prevent violating the minimum fiber bend radius of the cable.
