LAN connections are made by way of RJ-45 connectors on the front panel of each Module.
These connectors are shown in
Figure 3-12. Each connector has a green Link/Activity LED
and a yellow LAN speed LED (ON for 100 Base-T).
The gateway Module "LAN" ports and the SHUB8 "UPLINK" ports as well as the IP Keyset
LAN are terminated in the standard Media Dependent Interface (MDI) configuration
shown in
Figure 3-12. The SHUB8 "X" LAN ports are terminated in the mating MDIX
(crossover) configuration as shown in the figure. The SHUB8 can provide power over the
LAN with 48 VDC across pin pairs 4 & 5 and 7 & 8. This mates with the IP Keyset as
shown. The IP LCD 2P Keyset is equipped with a second LAN port to connect a PC or
similar device to a share LAN infrastructure. This connector is terminated in the MDIX
configuration mating to a typical PC with the straight cable.
All LAN wiring must use Category 5 Unshielded Twisted Pair (CAT 5 UTP) cable. No single
run of LAN cable should exceed 100 meters (about 328 feet).
