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.
