Summary | 0000415: The problem of the power supply of RT8 in the IVC. | ||||||||
Description |
The problem of the power supply of RT8 in the IVC happened twice(on 27/10 and 28/10). When the problem happened there were also no Ampls of the cross-correlations in band1,3,5,7. At the first time The problem had been solved by rebooting the dzb. At the second time the power supply of RT8 and the lantronics mss 485 LO steering unit had to be switched off and on to solve the problem. It should be looked at after the VLBI session is finished. |
||||||||
Additional Information |
On Wednesday Nov 7 2012, Harm Jan has replaced the Power supply of the RT8 section of the IVC. The lantronics mss 485 LO steering unit was not replaced yet. This has to be done by Teun, because it has to be configured to get the proper IP address. It can also be possible that the lantronics device is not causing the problem but that it is related to the power supply only. |
