Gigabit Fiber to Fiber Media Converter Module – Installation Guide

Troubleshooting 

General 

 

Ensure the module is securely seated in the chassis. The 
PWR LED on the module should be on solid. 

 

Ensure all cabling is of the correct type and is in good 
operating condition. 

 

Ensure both devices on either end of the fiber are compatible. 
If using a simplex fiber connection, ensure that you have both 
an Upstream (U) and Downstream (D) Media Converters. 

 

For dual-stranded fiber connections, ensure the RX and TX 
has been reversed between the two Media Converters.  

No connectivity 

If unable to get full connectivity with all DIP switches in the UP 
position, these methods are recommended for troubleshooting. 

Method 1 

1.  Turn off Fiber Negotiation (SW1 Down) on both media 

converters. Leave all other switches UP. 

2.  Connect the near end device to port MM1, the LK1 LED 

should be lit to indicate a good fiber connections. If the LK1 
LED is not lit, then check the fiber cable and the attached 
device. 

3.  Repeat step 2 for port MM2/SM2. 

4.  Return the media converter to the desired configuration. 

Method 2: 

The fiber connection can also be verified by configuring the remote 
media converter for loopback mode. The LEDs on both media 
converters should be lit. Data should pass through the local 
converter then over the fiber connection to the remote media 
converter. 

Note: If troubleshooting a CM-1000MM, setting the Auto-Config 
jumper (J5) to SW will ensure the DIP switches are being read.
