Refer to the next chapter, Understanding Indicators, for detailed infor-
mation about each of the hub’s LED indicators.
♦
Twisted-Pair Ports
Use any of these ports to connect stations to the hub. The ports are
MDI-X ports, which means you can use ordinary straight-through
twisted-pair cable to connect the hub to PCs, workstations, or servers
through these ports. If you need to connect to another device with MDI-
X ports such as another hub or an Ethernet switch, you should use a
crossover cable, or connect using the Uplink port (described below).
For more information about crossover connection, see the Crossover
Cables section on page 24.
♦
Uplink Port
The Uplink port is an MDI port, which means you can connect the hub
(or hub stack) to another device with MDI-X ports using an ordinary
straight-through cable, making a crossover cable unnecessary.
Port 1 and the Uplink port are really the same port, except that their
pinouts are different. Do not use both Port 1 and the Uplink port at
the same time.
