3.7 Connecting the interfaces
3.7.1 Connecting an Ethernet network
• Connect the Ethernet cable to the Ethernet interface (RJ45 sockets: LAN1, LAN2 or
LAN3.1/3.2) of the RFC 4072S.
The cable connects the RFC 4072S to a higher-level or lower-level Ethernet network.
• Use Ethernet cables according to CAT5 of IEEE 802.3 for operation with up to
100 Mbps. (LAN1, LAN2, LAN3.1, LAN3.2)
• For operation with 1000 Mbps (Gigabit), cables with four wire pairs (twisted pairs, eight
wires in total), which at least meet the requirements of CAT5e, must be used. (LAN1,
LAN2)
For the ordering data for the Ethernet cable, please refer to Section “Ordering data” on
page 230 .
