Bootup diagnostics also include a set of tests that are common with health monitoring diagnostics. The
bootup and health monitoring diagnostics are described in
Bootup diagnostics log any failures to the onboard failure logging (OBFL) system. Failures also trigger
an LED display to indicate diagnostic test states (on, off, pass, or fail).
You can configure Cisco Nexus 5000 Series switches to either bypass the bootup diagnostics, or run the
complete set of bootup diagnostics. See the

Health Monitoring Diagnostics

Health monitoring diagnostics provide information about the health of the switch. They detect runtime
hardware errors, memory errors, software faults, and resource exhaustion.
Health monitoring diagnostics are nondisruptive and run in the background to ensure the health of a
switch that is processing live network traffic.
