NI Diagnostic
Overview
The NI diagnostic verifies that the LANCE chip is operational.
The diagnostics also induce "forced errors" to ensure
functionality.
When the unit is powered on, limited testing is performed.
Complete testing of the NI diagnostics must be performed under
service mode.
Testing can be performed:
• Upon power-up
• In console mode
• In service mode
