Dear Spinlanders,
We recently had our Avance II 400 lose communication with our workstation.
On power up, we get a few LINK and STATUS LEDs on the CCU flashing but then
nothing, leaving the first and second STATUS LEDs lit and the second LED on
the LINK lit. Resetting the CCU gives no changes except on the STATUS which
settles into the same first and second LEDs lit. The LEDs on the workstation
ethernet port are green and amber/yellow and static, so we have power and
connection but no communication.
Does anyone know the normal sequence of LEDs that should light up for both
the LINK and STATUS LEDs? Is there a reference for the indicators?
We have so far swapped the CCU and PSM2 as well as bypassed the router plugged
in directly to the workstation.
Any assistance would be greatly appreciated.
All the best,
Rick
