    Note: If there JF does not switch on it may be because the flow in the chiller is not enough due to filter clogging. Check the display in the chiller. The minimum value is 4 l/min. If it is below that value, exchange the filter.

    A possible reason for connection problems is that the transceivers are not well plugged in the switch (in the rack) or that any of the optical fibers is not clean. If that is the case, when trying to run a scan we would get an error: "Error, reason: everything fine but no request to write any data", which means that the data of any of the modules or the pulse IDs are not being properly received.
