Overview Of Analyzing Failures Of Functionality - Alaxala AX6700S series Troubleshooting Manual

1. Overview

1.3 Overview of analyzing failures of functionality

The following table provides an overview of analyzing functional failures on the Switch.
Because communication failures in a lower layer might cause communication failures in an upper
layer, check the items applicable to lower layers.
