| Summary | 0000106: Bad contact dataconnectors (backplane and boards) | ||||||||
| Description | connector problems between backplain and boards | ||||||||
| Additional Information |
Gisteren (24 febr.) samen met Sjouke Zwier bezig geweest om de fouten in COR unit 3 te lokaliseren. Na lang testen en onderzoeken tot de conclusie gekomen dat de individule correlator borden geen fouten hebben, maar dat de problemen zich voor doen tussen het backplane en de borden. gevonden dat de data connectors geen goed contact maken. alle COR units moeten hierop gecontroleerd worden en cor 3 moeten we als eerste opnieuw afstellen. |
