3.
Place Jumpers J2 and J3 in the CLOSED position when there is a twisted pair cable connected to port 1 of
terminal block TB1. Each repeater has the ability to monitor for earth ground faults on the twisted pairs con-
nected to port 1of its terminal block TB1. Earth fault detection for any wiring at Port 2 of TB1 is done at the
next/previous repeater due to these wiring connections being connected to Port 1of TB1 at the next/previous
repeater. When no twisted pair wiring is made to Port 1 of TB1 jumpers J2 and J3 must be left OPEN at the
repeater. This would be the case when using fiber optic cable or when Port 2 of TB1 is only being used.
4.
On fiber optic repeaters, jumpers J4 through J9 are normally left OPEN. See IFP-RPT installation instruc-
tion (PN 9001-0061) for determining when to use J4 through J9. Fiber optic ports that are not used must
have their dust caps placed on the port.
5.
Based on the type of network repeater board chosen, run the twisted pair wiring /fiber optic cable to the next
network repeater using a BUS or style 7 (class A) wiring method. A combination of both repeater types can
be used. See Figure 5-6 on page 5, Figure 5-7 on page 6, Figure 5-8 on page 7, and Figure 5-9 on page 8 for
repeater wiring examples.
5.4.2.1
Network Repeater Cable Requirements
Cable requirements for wire runs between repeaters.
1.
All fiber cable must be multimode 62.5/125 micron cable with ST type connectors. It is important that the
cable be verified to contain no more than 8dB of loss including the connectors.
2.
Twisted pair wiring must be UNSHIELDED twisted pair conductor cable. The wire gauge must be 18 AWG
or larger. The maximum wire length is 3000 ft. between repeaters.
5.4.2.2
Unshielded Twisted Pair Wiring between Multiple Panels
Unshielded twisted pair wiring between multiple panels is shown in Figure 5-6. Class A wiring is shown with a
dotted line.
