Hello, I´m recently have installed a brand new one CCR 1072 and note that ether1 interface does not shown at interface tab… so I´ve upgraded to 7.1.5 and still vanished… the port doesn´t work and many others like sfp+1 or sfp+3 work with problems…
I have adopted an ether1 at my place. It showed up one day, tired and hungry and I gave it a home and love and a reason to live.
Suggesting you send the rest of its kin my way and thus you will not be searching for ether1 any more. Will pay postage…
It is a joke, maybe a bad one. But I liked it.
If ether1 is not present it is most likely a defect. It is via a pci-e controller attached to the Tilera. I would get a rma.
Are you saying the unit is defective?
Report as supout to MT with your findings and work with them directly to see if the unit needs to be replaced.
I cant imagine you are using bad cables.
IMO , I suspect there may be a problem with the PCIe x1 controller ( circled in red in my image post here ).
Your options are:
Continue to use it as-is ( if you don’t need the ethernet ).
RMA it to where you purchased it ( if it is still under warranty ).
Put it in a refrigerator for 15 minutes ( not the freezer ), If the Ethernet port shows up when the board is cold , then it might be the PCIe x1 controller is starting to go out , or a hair-line cold solder joint near the PCIe X1 controller.
Use a strong magnifying glass and follow all of the circuit board board traces from the Ethernet connector to the PCIe X1 controller chip and examine the traces to/from the PCIe X1 controller chip.
Note - most networking problems are at the physical L1 level. Thus look of loose solder connections and hair-line-thin shorts and look for any rounded ( blown capacitors ).
FYI - Many years ago ( late 1970s ) , I was a electronics board repair tech - so this info might help …
If you resolve the problem , please post what you did to resolve it.
Also , try ROS downgrading the board ( don’t forget the sy ro pr up y reboot part ).
Hi Tom! I will try the refrigerator because I well known that trick. Many hard drives has back to live after that so will try… since nothing to loose. I will post if work or not. If fails will send it to RMA.
Thanks for all info!
