May 21, 2008 online meeting minutes

present: Sergey Boyarinov, Sergey Pozdnyakov

During last month several hardware failures were observed:

- PMC broke in tage3 and sc2 - replaced, will be tested in test setup
- 4 timing discriminators 2313 in CC broke after accidental power recycle - replaced; removed boards were tested in test setup
    and appeares to be fine; more tests will be performed
- wrong signal polarity was discovered on output from new trigger - swapped cable
      installed (fortunately data were fine, but it maybe desasterous error !)
- power supply broke in croctest10 - replaced, sent to repair to WIENER

Also old NIM bin send to repair to ORTEC

Software problems:

- ROCs crashes, EB have to be restarted every time after ROC crashed; it is still unclear why ROCs are crashing
    occasionally, it can be different reasons; internal monitoring was developed to debug several software loops
    inside ROC and PMC, it will be activated in an attempt to get more detailed information; EB should be able
    to recover on 'reset' transition;

- preshower setup problem: slow download, prestart etc; change CPU did not help. jlab IP address did not help, will study

- low network speed in pmc880 and pmc280, while 2800 is good - another device; will study at summer
