Twisted-Pair Ethernet Cable-Type Connectivity
The following types of TPE cables can be connected to the 8-pin TPE connector:
■
For 10BASE-T applications, shielded twisted-pair (STP) cable:
■
Category 3 (STP-3, voice grade)
■
Category 4 (STP-4)
■
Category 5 (STP-5, data grade)
■
For 100BASE-T applications, shielded twisted-pair category 5 (STP-5, data grade)
cable.
LOM Serial A and Serial B Ports
The LOM Serial A and serial B ports use RJ-45 connectors (
). The LOM
Serial A port is also known as the system controller serial port.
