Executive summary
VRTX chassis has different logging mechanism to capture all the events on the chassis. The event
could be configuration change or any critical or non-critical. The VRTX Chassis has different
logging mechanism like Chassis log, SEL Log, LCD, Remote System Logging. The events could be
identified from the logs and the recommended action can be performed as stated on the logs,
especially on the Chassis logs to overcome the critical events.
Apart from the recommended action on the logs, Administrators can perform some diagnostic and
recovery mechanism to overcome events. VRTX Chassis has a diagnostic console which could be
used for identifying any network related issues or any other similar critical events. The different
LED patterns on the CMC helps Administrators in troubleshooting the activity of the Chassis
Controller. LEDs located on other components such as PSU, PCIe Adapter, and Storage Controller
assists in their diagnoses.
