7. Feed sub-units through opening in shelf and temporarily coil sub-units loosely inside shelf.
8. Rotate locknut as required to allow it to pass through the opening and enter shelf.
Note:
It may be necessary to temporarily remove a plug from an adjacent opening to provide sufficient
clearance for locknut to be inserted through opening.
9. Insert threaded body of cable gland into opening and tighten locknut onto threaded section to secure trunk
cable to shelf.
10. Using one of the methods described below, route and secure the trunk cable from the cable gland back to
the rack.
Method A
1. Working back from where the fiber cable enters shelf (at a cable gland), carefully loop cable over rear fiber
management bar and then to outside of shelf slide on opposite side of panel from cable entry point as
shown. Maintain cable in as small of a radius as possible while not exceeding minimum bend radius for
cable. Secure fiber cable to shelf slide in at least two places using cable ties or hook-and-loop straps
threaded through slots and punches provided in rails.
Do not secure cables to fiber management bar.
2. From shelf slide, route cable to equipment rack and loosely secure cable to rack upright approximately
3 inches (76mm) above or below shelf, using a cable tie or hook-and-loop strap.
Note:
Do not exceed minimum bend radius for fiber cable.
3. Verify that shelf retracts and extends fully before proceeding.
4. The ribbon cable of the panel bus jumper may slide in the corrugated tubing.
Method B
Note:
This method reduces the slack loop length at rear of shelf but it requires an open space of at least 1U
above the shelf to work.
1. Working back from where the fiber cable enters shelf (at a cable gland), carefully loop cable over rear fiber
management bar and then across shelf slide on opposite side of chassis from cable entry point as shown.
Maintain cable in as small of a radius as possible while not exceeding the minimum bend radius for the
cable.
Do not secure cables to fiber management bar or drawer slide.
2. Route cable to equipment rack and loosely secure cable to rack upright approximately 3 inches (76mm)
above or below shelf, using a cable tie or hook-and-loop strap.
3. Verify that shelf retracts and extends fully before proceeding.
4. The ribbon cable of the panel bus jumper may slide in the corrugated tubing.
Step 5
– Connect Cables to MPO Adapters
1. Remove protective dust covers from MPO connectors on the cable.
2. Prior to installation, clean all MPO connections per the m
anufacturer’s recommendations.
3. Grasp connector by its boot, near the base of connector. Insert MPO connector into coupler until it clicks into
place.
Note:
The MPO connection is keyed. The polarized tab on the connector fits into the opening on a coupler
on adapters.
4. I
nsert each of the trunk cable’s MPO connectors into MPO couplers on adapters.
5. Route sub-units so that slack length is contained and so as to avoid tight bends as the connectors are
terminated into the adapter panels.
Note:
To unplug an MPO connector, grasp the ribbed sleeve section and pull connector out of coupler.
Do not pull on the boot to unplug an MPO connector.
