Home / Huijue Switch Optical Port Error
If two or more optical modules have the same SN, bogus optical modules are used. Based on typical issues encountered with optical modules in daily switch applications, this document summarizes basic troubleshooting steps for resolving common faults: 1. This document describes how to check the switch interface or port status and how to locate an interface physically down fault and restore the interface to the up state. Verification events including pluggable authentication, verification transceiver optical power, the signal transmission quality.
