Checking Hardware Diagnostics
Loopback diagnostic tests are available for testing the adapter hardware.
These tests provide access to the adapter internal and external
diagnostics, where packet information is transmitted across the physical
link. For instructions and information on running tests in an MS-DOS
environment, see Chapter 12, “User Diagnostics” on page 155. For
Windows environments, see “Running Diagnostic Tests” in the Broadcom
Advanced Control Suite 3 User Guide which you can download from the
Allied Telesis website.
