16 CHAPTER 1: INTRODUCING THE SWITCH 4200G FAMILY
Figure 3 Switch 4200G 48-Port—front view
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.
10/100/1000BASE-T
Ports
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.
