6.4 Mixing Wire & Fiber on One Network
In some networks, it may be necessary to mix twisted-pair wire and fiber-optic cable. Use a HS-NCM-WMF/WMF-2 or HS-NCM-WSF/WSF-2 as an
interface between wire and fiber.
Fiber ports are not polarity sensitive. However, port-to-port wiring for the HS-NCM wire connections are polarity sensitive. When converting from a
wire to fiber network, it may be necessary to change the port designation for the wire connection on the HS-NCM-WMF/WSF/WMF-2/WSF-2. To
change the wire port designation, the HS-NCM parameters must be changed via VeriFire Tools. For instructions on how to change the HS-NCM
parameters, refer to “HS-NCM Configuration” on page 6.
See Section 2.1, “Network Communications Module for Fiber (HS-NCM-MF, HS-NCM-SF, HS-NCM-MFSF)” for requirements and restrictions on
the use of fiber-optic cable. See the High-Speed
Noti•Fire•Net Manual for a discussion of all compatible configurations.
