Restarting the LTU

Look to the QPLL led in the Link RX, if this led is flashing then you have a LTU problem, probably because you had a power cut and you need to restart reset the LTU So :

ssh to lnxpool31.cern.ch open exceed and then run the folwing commands:
initttc
export DISPLAY= your_computer_name:0
vmecrate ltu

then you should see a panel with the LTU config, just click ttcreset button and then look and see if the QPLL led in the link receiver is on. That's all folks
