4.4.4.Connecting the Ethernet Interfaces of SMUB

The SMUB of 3P@C 4450E has an RJ-45 Ethernet interface (10/100Base-TX interface). In addition, the uplink interface sockets on the SMUB can be installed with the uplink interface module DS-4TXB/DS-4ITX which provides 4 RJ-45 Ethernet interfaces. The RJ-45 network interface provided by 3P@C 4450E has the interface polarity automatic calibration function. It can be connected to the other network devices by the C5 UTP (Unshielded Twisted Pair) or STP (Shielded Twisted Pair).
