10BASE-T Ports
The sixteen 10BASE-T ports are located on the front panel of
each switch. These ports are labeled with an “x” to indicate that
they have a built-in crossover.*
If a 10BASE-T port is connected directly to an Ethernet server,
power user or another switch, it will provide the device with a
dedicated bandwidth—20 Mbps in full-duplex mode or 10 Mbps
in half-duplex mode. If the port is connected to an Ethernet
hub, it will provide the hub with a 10 Mbps bandwidth that can
be shared by multiple users.

100BASE-TX Port(s)
Models SMC6516TT and SMC6516TF are equipped with at least
one 100BASE-TX port (port 18). Port 17 on model SMC6516TT
is another 100BASE-TX port.
Like the 10BASE-T ports, each 100BASE-TX port is labeled with
an “x” to indicate that it has a built-in crossover.* In addition,
the 100BASE-TX ports support Auto-Negotiation, so the optimum
operating mode—half or full duplex and 10 or 100 Mbps—is
selected automatically.
* Workstations and servers can be connected to these ports with
straight-through cable. When connecting hubs and other switches to
these ports, a crossover cable will probably be necessary. Please see
Appendix A for cabling information.
