When the ASDEX was turned off; within a minute the radar scope in the Tower Cab flashed with a yellow bar towards the top and the mode said failed. I do not know what that means. It will normally say Mode: normal. In the TRACON they had something in red indicating a failure on two scopes and had to transition to ESL mode. This happened during the national ASDE-X outage to fix a clock issue. Management was aware of the occurrences. Nothing was logged by management. Airway Facilities was not aware of it. A [report] was filed on this and I believe it is closed. The previous [report] was written questioning if the ASDEX outage caused this. The response was 'NO' because they are two independent systems. However; something happened. It seems more than coincidental that all of this took place almost immediately after the ASDEX was taken down. We have spoken with the local Tech Ops guys and agreed a new [report] should be filed to see if this happened anywhere else. The information is no longer available as it only lasts 45 days.I do not understand how this could not have been logged and checked in to. We lost two radar scopes and something occurred on a third one. This type of thing rarely happens and now the data is lost. I would like to know if anyone else in the country had anything similar to this happen. It is my understanding that only one report was originally filed on the outage.
During a scheduled ASDE-X outage this Tower and the TRACON also experienced Primary Radar software outages on some of their radar displays requiring the back-up system to be necessary.The reporter states that the appropriate maintenance office was not notified of the Radar display outages. The reporter wanted to know if this was a coincidence or a known issue that the controllers should have been briefed on.
