Therefore, isolate your card by terminating both ends of the bnc tests fail, it could mean you are connected to a busy network. controller and transceiver chips. Again, if any of these The last three tests check the integrity of the Ethernet in a 'noise free' environment. This isolates your card, and allows loopback to take place terminating both ends of the bnc T-connector with 50-ohm loads. the rest of the network by taking the coax cable off and If the problem persists, try disconnecting your card from 3. check to see that the bnc connector is twisted onto the board 2. remember to disconnect from network services 1. make sure your coax cable is terminated at both ends of the network If the cable check failed, there could be a few reasons: be a rare occurance, but if it does happen, call technical support. of the components on the card are malfuctional. This should If either of the first two tests fail, this indicates that some read on. the rest of this section. If however there were any failures, sure your Ethernet card is functioning properly, and skip After running loopback, if all the tests passed, you can be tests will be meaningful. Twisted-pair users can run loopback, but only the first two Note: Loopback testing applies only to coax networks. tests its interface to the cable. important since loopback testing resets your Ethernet card and services (e.g. AppleShare, Internet Router, etc.). This is very loopback. Before doing this, make sure and log off any network If a card can be seen, the next step is to perform To see which cards are in the machine, look in the slots area. configured properly. 'Card Info' area to make sure your Ethernet card is The first step in using Inside Ethernet is to look in the SE, LC, Si, and SE30, are supported by Inside EtherNet. All Ethernet cards which include: the Nubus family, This utility is an aid to diagnosing your Ethernet card. Inside Ethernet
