Only half-duplex mode is supported. Ensure that
your hub or switch is set to half-duplex.
The speed of the 10/100Base-TX card must match the speed setting
of the hub or switch port to which the card is connected. The card
only runs at one speed at a time. The card only senses the speed
the first time the system is booted up. If, for example, you remove
the cable from the card's connector and then reconnect
it, the card will not automatically sense the hub or switch speed.
To verify the speed selection, use the LED indicators on the front
of the 10/100Base-TX card as seen in the EISA 10/100Base-TX/9000
Quick Installation or run lanadmin and check
the link speed and duplex mode at the LAN Interface Status Display.
To change the speed after the system is running, use the reset
command within the lanadmin command.
