Red light on the optical port of the 100Mbps switch
Move the cable to a known good port to troubleshoot a suspect port or module. The show module command can indicate faulty, which can indicate a hardware problem. The SFP/Media Converter is designed for easy use in optical fiber transmission. The table describes the LED status indicators for Ethernet modules or fixed-configuration switches: Ensure that both sides have. System activity and status can be determined through the activity of the LEDs on the switch. The status LEDs can display solid amber or flash during boot, POST, or other diagnostic tests. Most likely cause is either your switch port is only 100Mbps or your cable is only Cat5 = 100Mbps. It might also be a broken cable or just loosely plugged in, so you can try unplugging and plugging it back in.

How to view optical module information on a Cisco switch
Execute the following command to view detailed interface and optical module status: show interface <interface-type> <interface-number>Execute the following command to view detailed interface and optical module status: show interface <interface-type> <interface-number>This article provides instructions on how to view the Optical Module Status on your switch through the Command Line Interface (CLI). The Cisco Small Business Series Switches allow you to plug in a Small Form-factor Pluggable (SFP) transceiver in their optical modules to connect fiber optic cables. When optical modules operate on a switch, it is usually necessary to read the module's internal information to understand its working status—such as connection status and real-time metrics like optical power and temperature. Additionally, identifying module information helps detect coding. This guide gives a practical, CLI-focused workflow for checking SFP health and diagnostics on Cisco switches, shows the exact commands you'll use, explains what the numbers mean, and compares OEM (Cisco) vs third-party modules so you can pick the right SFP module supplier for reliability and cost.
