NPT-1020 Installation and Maintenance Manual

5.18.2 Connecting Alarm Cables

The alarm cable is connected to the corresponding ALARMS connector on the NPT-1020.
To connect the alarm cable:
1. Connect the connector of the alarm cable, in accordance with the frame installation plan and the
cable tags, to the ALARMS connector on the NPT-1020.
2. Secure the cable connector to the ALARMS connector with the cable connector screws. Tighten the
screws manually. If you cannot reach the screws with your hands, use an adjustable-torque flatblade
screwdriver (maximum blade size 0.6). Set the tightening torque to 40 N cm to 44 N cm.
3. Bend the cable and route it above the NPT-1020 and adjacent to the left side cable supports.
4. Use cable ties as required to fasten the cable to the cable supports.
5. Connect the free ends of the alarm cable in accordance with the frame installation plan and the cable
tags to the customer's facility.

5.18.3 Connecting Optical Fibers

All optical fibers in the NPT-1020 platform are connected to the LC connectors on the SFP/XFP transceivers.
Before you start:
C
AUTION: Make sure that all the optical connectors are closed at all times with the
appropriate protective caps or with the mating cable connector. Do not remove the protective
cap until an optical fiber is connected to the corresponding connector, and immediately install
a protective cap after a cable is disconnected.
The minimum bending radius of optical fibers is 35 mm. Sharp bending of fibers may degrade
the optical transmission characteristics.
To connect an optical fiber to a NPT-1020 module/card:
1. Insert the end of the fiber into the upper end of the flexible tube and pull it at the lower end, near the
NPT-1020.
2. Bring the end of the fiber to the LC connector on the designated module/card. Leave some slack to
prevent stress.
3. Thoroughly clean the connectors of the optical fibers, using an approved cleaning kit.
4. Remove the cover from the module/card connector, and connect the fiber connector to it.
5. Repeat Steps 1 through 4 for all optical fibers to be connected to NPT-1020 modules/cards.
