Establishing the Ethernet Connection
The Ethernet port is 10/100BaseT auto-negotiating. Set your hub or switch to
auto-negotiate (if applicable) before making the Ethernet connection. Plug the
Ethernet cable into the Ethernet RJ45 port on the UIM faceplate. Verify the
connection: solid illumination of the Lnk LED on the UIM faceplate indicates an
Ethernet link has been established. If the Lnk LED is illuminated but not the 100
LED then a 10 Mbps link has been established. If the 100 LED is also illuminated,
then a 100 Mbps link has been established.
For most applications, the UIM-10/100 connects to a router or a PC using a
straight-through Ethernet cable and to a hub or a switch using a crossover
Ethernet cable. For any other connection combinations you must verify the pinout
of the Ethernet device into which you are connecting the UIM-10/100 in order to
determine which type of cable is required.
