NPT-1020 Installation and Maintenance Manual
To connect PCM traffic cables to an ICP:
1. Arrange the PCM traffic cables and route them to the rack side rails.
2. Pull one end of each PCM traffic cable to the level of the SM_10E/EM_10E card.
3. Bend the cable and thread it through the side cable guides of the rack and through the appropriate
opening near the shelf until the cable connector is positioned against the appropriate place. Use cable
ties as required to fasten the cable to the rack side rails.
4. Use a cabling diagram of the site to associate the SM_10E/EM_10E traffic module connectors with the
appropriate ICP connections.
5. Connect the cable connector to the corresponding connector on the SM_10E/EM_10E traffic module
front panel.
C
AUTION: Do not exert excessive tightening torque to secure the cable connector, as this may
damage the SM_10E/EM_10E traffic module.
6. Secure the cable connector to the SM_10E/EM_10E traffic module 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 is 0.6). Set the tightening torque to
40 N cm to 44 N cm.
7. Pull the other end of each PCM traffic cable to the level of the ICP.
8. Bend the cable and thread it through the side cable guides of the rack and through the appropriate
opening near the ICP until the cable connector is positioned against the appropriate place. Use cable
ties as required to fasten the cable to the rack side rails.
9. Connect the cable connector to the SCSI-36 connector on the ICP front panel.
10. Secure the cable connector to the connector marked as J1 on the ICP front panel 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 is 0.6). Set the tightening torque to
40 N cm to 44 N cm.
C
AUTION: Do not exert excessive tightening torque to secure the cable connector, as this may
damage the ICP.
4.9.6.3 Routing and Connecting Electrical Cables for ICPs
Connectors on the ICP_VF panel for external interfaces are RJ-45 connectors. Connectors on the ICP_V24
panel for external interfaces are 15-pin D-type connectors and 9-pin D-type connectors. Connectors on the
ICP_V35 panel for external interfaces are M34 connectors. For a detailed description of the ICPs, see the
NPT Product Line Reference Manual.
A VF cable is an electrical cable with an RJ-45 connector on one end and the other end open. Each cable has
six wires and can be used for one channel of the following types of interfaces:
