SK-NIC Installation
2. Use the 6-pin cable included with SK-NIC to connect the IFP-75 to the SK-NIC. The 6-pin cable must be run in conduit between
cabinets. Refer to Figure 5.1.
3. Each SK-NIC has the ability to monitor for earth ground faults on the twisted-pairs connected to Port 1 of its terminal block TB2. Earth
fault detection for any wiring at Port 2 of TB2 is done at the next/previous SK-NIC due to these wiring connections being connected to
Port 1 of TB2 at the next/previous SK-NIC.
4. Unused optic ports on fiber loop modules must have their dust caps placed on the port.
5. Based on the type of data medium chosen, run the twisted pair wiring/fiber-optic cable to the next SK-NIC using a Class B or Class X
wiring method. A combination of both medium types can be used. See Figure 5.6 through Figure 5.9 for SK-NIC wiring examples.
