10/100/1000BASE-T Ports

WARNING: RJ-45 Ports. These are shielded RJ-45 data sockets. They cannot
be used as standard traditional telephone sockets, or to connect the unit to a
traditional PBX or public telephone network. Only connect RJ-45 data
connectors, network telephony systems, or network telephones to these
sockets.
Either shielded or unshielded data cables with shielded or unshielded
jacks can be connected to these data sockets.
The Switch 4200G has 12, 24 or 48 auto-negotiating
10BASE-T/100BASE-TX ports configured as Auto MDIX (crossover). When
auto-negotiation is enabled these ports automatically operate in MDI or
MDIX mode as needed. These ports provide 10/100/1000 Mbps
full-duplex connections to other Gigabit Ethernet devices. Full-duplex
allows packets to be transmitted and received simultaneously which
effectively doubles the potential throughput of a link.
These ports require either straight-through or cross-over Category 5
cables with RJ-45 connectors at each end. The maximum UTP cable
length is 100 m (328 ft) over Category 5 cable.
The 10/100/1000BASE-T ports will auto-negotiate the appropriate speed.
