Dual-Speed Stackable Hubs User’s Guide

♦LED Indicator Panel

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.
