Cisco Nexus 3548 series - Configuring Online Diagnostics

When you insert an expansion module into a running switch, a set of diagnostics tests are run. The following
table describes the bootup diagnostics for an expansion module. These tests are common with the bootup
diagnostics. If the bootup diagnostics fail, the expansion module is not placed into service.

Configuring Online Diagnostics
You can configure the bootup diagnostics to run the complete set of tests, or you can bypass all bootup
diagnostic tests for a faster module boot up time.
We recommend that you set the bootup online diagnostics level to complete. We do not recommend bypassing
the bootup online diagnostics.
