4.11 LAN Connection
4.11.1 LAN Connection for the Main Unit
Connecting the Main Unit to the LAN
The PBX is equipped with a LAN port for connecting to a LAN so that IP telephones (IP-PTs, IP softphones,
SIP phones), IP-CSs, PCs and a CTI Server can be connected on a private IP network. When the PBX is
connected to the LAN for the first time, you must assign IP addressing information to the PBX. See
"5.4 Programming the PBX" for instructions.

Note
•
Use an Ethernet cable with an RJ45 connector for connection to a switching hub. The cable should be
a CAT 5 (Category 5) or higher for 10BASE-T/100BASE-TX, or CAT 5e (Enhanced Category 5).
•
Make sure that all CAT 5/CAT 5e cables in use are not over 100 m in length.
•
Make sure to set the port of the switching hub that connects to the card to operate under "Auto
Negotiation" mode.
•
Make sure to create a spanning tree for LAN connection in order to prevent loops from occurring in a
multi-bridged environment. Otherwise, some packets may circulate for long periods of time and
eventually PBX performance system may degrade.
