LAN
Connections
LAN connections are made by way of RJ-45 connectors on the front panel of each Module.
These connectors are shown in Figure 4.5.1.6-1. 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 POE8 “UPLINK” ports as well as the LIP Phone LAN
port are terminated in the standard Media Dependent Interface (MDI) configuration shown in
Figure 4.5.1.6-1. The POE8 “
X
” LAN ports are terminated in the mating MDIX (crossover)
configuration as shown in the figure. The POE8 can provide power over the LAN with 48 VDC
across pin pairs 4&5 and 7&8. This configuration mates with the LIP Phone as shown in the
figure. Finally, the LIP-7016D/7024D/7024LD and LIP-8012D/8024D/8040L Phones are
equipped with a second LAN port, designated “PC” to connect a PC or similar device allowing a
shared LAN infrastructure. This connector is terminated in the MDIX configuration mating to a
typical PC with a straight cable.
All LAN wiring should use Category 5 Unshielded Twisted Pair (CAT 5 UTP) cable. No single
run of LAN cable should exceed 100 meters (about 330 feet).
