Board Installation
Troubleshooting
If the adapter cant connect to the network:
•
Make sure the cable is installed properly. The network cable must be securely attached
at both RJ-45 connections (adapter and hub). If the cable is attached but the problem
persists, try a different cable. The maximum allowable distance from adapter to hub is
100 meters. If youre directly connecting two computers (no hub), use a crossover
cable. Most hubs require a straight-through cable, while most switches require a
crossover cable (see your hub or switch documentation to verify). See the Cabling
Information README file for more information on crossover cables.
•
Check the LED lights on the adapter. The onboard cable connector has
two diagnostic LEDs. These lights help indicate if theres a problem with the
connector, cable, or hub. The table below describes the LEDs, and the drawing on the
next page shows their location.
•
Make sure youre using the correct drivers. Make sure youre using the drivers that
come with this adapter. Drivers that support previous versions of the Intel PRO/100+
Management Adapter do not support this version of the adapter.
•
Make sure the hub port and the adapter have the same duplex setting. If you
configured the adapter for full duplex, make sure the hub port is also configured for
full duplex. Setting the wrong duplex mode can degrade performance, cause data loss,
or result in lost connections.
