The following components are found on the front and back panels of the
hubs:
♦ Ethernet Ports
Used for connecting the hub to network devices using 10BASE-T
shielded or unshielded twisted-pair cable. The X label marked on each
port means the ports are MDI-X ports, which connect to workstations and
servers using straight-through cables and to other hubs using crossover
cables.
♦ Port 1 Uplink Switch
Converts port 1 to an uplink port to allow you to connect the hub to an
Ethernet switch or another hub with an ordinary straight-through cable
instead of a modified crossover cable.
♦ RS-232 Console Port (manageable models only)
Used to connect the master hub to a network management station for out-
of-band communication, or for simple management using the console
interface. The console port has a standard 9-pin RS-232 female
connector.
