CHAPTER 5: Self-Test and Diagnostics
• Node address
• Model name and hardware version
• Date of manufacture
• Serial number
If the Adapter is not properly connected or not powered on, the following
message is displayed:
Adapter not connected or not powered.
After the information above is displayed, additional tests are performed.
These tests check the internal components of the Adapter, the cable circuitry
up to the MAU (ring), and the Adapter’s ability to integrate within the ring.
The diagnostics begin by identifying the parallel port’s address and IRQ
number. During the information display, the EEPROM and other internal
components are checked for proper operation.
The Bring Up Test checks the communication processor and its peripheral
devices such as the RAM. It also tests the integrity of the software downloaded
to the processor.
After the Bring Up Test, the processor is ready for initialization, which
checks the interrupt logic and the connection between the PC and the
communication processor. The initialization test also tests the internal cable
circuitry of the Adapter.
During operation, many Token Ring tests are performed, such as physical
insertion test, address verification tests, and ring poll participation. These
tests check the integration between the Adapter and other ring members.

IAGNOSTICS
The diagnostics portion of the STRDIAG program activates a single set of
adapter tests. However, in order to thoroughly test the adapter, you may want
to run the tests continuously. The continuous diagnostics option activates
those tests.
Once activated, all tests are run in a loop. The display indicates the last run
results of each test, the number or tests performed successfully, and the
number of test failures, if any. The tests can be terminated at any time by
pressing any key.

The Adapter is software-switchable for operation on 16-Mbps or 4-Mbps
Token Ring networks. The Adapter is preconfigured to operate at 16 Mbps.
This option provides the user with the ability to change the current value.
