Twisted-pair Jacks
Use these jacks connect stations to the hub. These are MDI-X (Medium Dependent Interface, Cross-Wired) jacks, which means you can use ordinary stright-through twisted-pair cables to connect user mechines and servers to the hub through them. If you need to connect another device with an MDI-X jack, such as another hub or an Ethernet switch, you should use a crossver cable, or make the connection using the Uplink jack.
Uplink Jack
The Uplink jack is an MDI-II jack, which means you can connect the hub (or a hub stack) to a device with an MDI-X port using an ordinary straight-through cable, making a crossover cable unnecessary.
Port1 and the Uplink port is really the same port, except thar their pinouts are different. Do not use both Port-1 (1X) and the Uplink port at the same time.
