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 ver-
sions of the Intel PRO/100+ Manage-
ment Adapter do not support this
version of the adapter.

Make sure the hub port and the
