DAQ System UpgradeDAQ System Upgrade
Upgrade was needed forUpgrade was needed for Standard Operating System on all Online PC
Stable Software Behaviour Controlled Installation/Replacement Procedure User Friendly
DATE Software update Better Memory management allowing larger
buffers-> Increase the number of events per spill
Delicate operationDelicate operation No service interruption allowed Need rapid back up procedure in case of
problem

The CAMAC Crate The CAMAC Crate IncidentIncident
The IncidentThe Incident In December 2009, after TOF2 installation, the
power supply for the CAMAC crate holding TOF Discriminator failed (over current)
The diagnostic of the failure was not simple
After unsuccessful replacement of thePower supply and the fan tray, it wasdecided to replace the full crate
=> Re-cabling of all the boards !

The CAMAC Crate The CAMAC Crate IncidentIncident
The ConsequenceThe Consequence Half of the ECL cables re-plugged in
reverse polarity Christmas Run cancelled
The Sequels The Sequels All boards and cables properly labeled New cables prepared to avoid single
pair connections A new CAMAC board has been
designed and produced to simplify the layout and reduce the current
Detailed layout and cabling drawing under way

Event BuildingEvent Building
The synchronization problem between The synchronization problem between the two crates persiststhe two crates persists
We incriminate the PCI/VME interface It couldn’t be replaced because
all the spares used for the mirror DAQ system Massive failure of boards: 4 out of 10 boards had to
be send for repair
In the meanwhileIn the meanwhile Online monitoring histogram allow to spot the
problem A VME and PC power cycle solve it temporarily Shifter’s attention is required
