10/100TX UTP Ports

The twenty-four (24) 10/100TX UTP ports auto-negotiate both 10BASE-T and 100BASE-TX connections. . All ports like all normal hub ports are congured as MDI-X. However, port 24, supports both MDI-X and MDI port conguration.

Uplink Port

The uplink port provides cabling exibility on UTP port 24 for connecting to a workstation NIC or cascading to another hub. Although these ports have two (2) UTP connections, MDI and MDI-X, only one port may be used.

Notes on MDI and MDI-X Ports

MDI (Media Dependent Interface) is the standard that denes the mechanical and electrical conguration of a UTP port. For any two devices to communicate with each other, the transmitter of one device must be connected to the receiver of the other device.
