• Create cross-connections:
  curl --cookie PHPSESSID=ue5gks2db6optrkputhhov6ae1 -X POST --header "Content-Type: application/json" --header "Accept: application/json" -d "{\"in\": \"1.1.1\",\"out\": \"6.1.1\",\"dir\": \"bi\",\"band\": \"O\"}" --user admin:pxc*** "http://osw-daq-calients320.pcdsn/rest/crossconnects/?id=add"
• Activate cross-connections:
  curl --cookie PHPSESSID=ue5gks2db6optrkputhhov6ae1 -X POST --header "Content-Type: application/json" --header "Accept: application/json" --user admin:pxc*** "http://osw-daq-calients320.pcdsn/rest/crossconnects/?id=activate&conn=1.1.1-6.1.1&group=SYSTEM&name=1.1.1-6.1.1"
  • This doesn't seem to work: Reports '411 - Length Required'
    Use the web GUI for now
• List cross-connections (easier to read in the web GUI):
  curl --cookie PHPSESSID=ue5gks2db6optrkputhhov6ae1 -X GET --user admin:pxc*** 'http://osw-daq-calients320.pcdsn/rest/crossconnects/?id=list'
• Save cross-connections to a file:
  • Go to http://osw-daq-calients320.pcdsn/
  • Navigate to Ports→Summary
  • Click on 'Export CSV' in the upper left of the Port Summary table
  • Check in the resulting file as lcls2/psdaq/psdaq/cnf/BOS-PortSummary.csv

High-speed repeater configuration

High speed repeater, located on the AMC cards, which repeat (clean) the link from/to SFP/FPGA, have to be configured. The equalizer default value does not provide a safe environment and link might not lock with this configuration.

How to use (after loading conda env.):

python pyxpm_hsrepeater.py --ip {XPM_IP_ADDR} --xpmid {XPM_ID} --link {AMC_LINK[0:13]}

What:

• Runs a equalizer scan and reports the link status for each value
• Set a value where no error have been detected (do not look for the best position / middle of a window)
