LAN Ports
The LAN ports (LAN1, LAN2 and LAN3) support 10 MBit/s and
100 MBit/s transfer rates in half duplex or full duplex operating
mode. You can integrate Forum 523/524 into your company’s net-
work (LAN, Local Area Network) via the LAN ports (Ethernet ports,
here provided as RJ45 sockets). This enables you to use
Forum 523/524 for VoIP telephony, to operate the Web console or
to use the Forum 523/524 as an IP router for connection to the
Internet, among other things.
Transfer rates and operating modes are switched automatically
(“Auto-Sensing function”). Connections requiring a crossover Eth-
ernet connection cable are also automatically switched. You can
therefore also use a uncrossed Ethernet connection cable to con-
nect to a hub or switch. For VoIP application, a switch device is
required.
An Ethernet connection cable (twisted pair cable in accordance
with 10BaseT or 100BaseTX) may be up to 100 m long. Safe oper-
ation with 100 MBit/s transfers requires the use of category 5
cables and connecting sockets. Use a shielded Ethernet cable (STP
cable, Shielded Twisted Pair cable).
There is an internal Ethernet switch with several ports on the
Forum 523/524’s main board. The switch is connected to LAN1,
LAN2, LAN3 and slot 2. The CPU provides two separate Ethernet
interfaces/ports internally. One of these interfaces/ports is con-
nected to the LAN ports, the other to the WAN port.
Position of the LAN ports (internal switch not displayed here)
The following Ethernet ports are on the main board:

connection to an external Internet Router.
