Using TroubleShooter Diagnostic Software
Running other TroubleShooter tests
The Loopback and Bandwidth Utilization tests are available in addi-
tion to the three default tests for validating the EN/SC adapter.
Running the Loopback test
The Loopback test verifies the operation of the major components
of the interface circuitry, the adapter, the serial network interface,
and the thin port transceiver by transmitting and receiving special
packets.
When using the Mini EN/SC Adapter, disconnect the thin Ethernet
cable and attach a T-connector. Terminate each end of the T-connec-
tor with a 50 ohm terminator.
To run the Loopback test, perform the following steps:
1
Click the Loopback test checkbox to select the test.
2
Click
TEST
to start the loopback test.
3
If the first test fails, click
REPEAT
.
If the tests are “passed” successfully, everything is operat-
ing properly.
If you leave the Macintosh connected to the network during the
Loopback test, the test may fail due to packet collisions. This does
not indicate the equipment is faulty. Repeat the test by clicking
REPEAT
. You need only one successful test run to verify proper
product operation.
If the Loopback test fails repeatedly, please call Technical Support.
