Situation:
“Module not recognized”
The 86100A will (sometimes) display this error message if the following
condition occurs.
1. If you power on the 86100A when there is a Clock Recovery Module in the
left slot and a electrical or optical module in the right slot then the error
2. message “Module not recognized” will appear. This does not occur on all
86100A mainframes.
3. If the 86100A mainframe is powered on and there is a electrical or optical
module in the right slot inserting the clock recovery module into the left slot
can cause the error message “Module not recognized”
Solution/Action:
Return to the Lightwave division only. This upgrade is covered under warranty.
This modification involves changing the value of one resistor, adding a resistor and capacitor to
the clock line on the digital interface board. These are surface mount components and must be
properly soldered. This is a “Return to Factory” only .
