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.
You can connect either shielded or unshielded data cables with shielded
or unshielded jacks to these data sockets.
The Switch 4200G provides 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
connections allow packets to be transmitted and received simultaneously,
which effectively doubles a link's potential throughput.
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 auto-negotiate the appropriate speed.
