Handover Issues

CRDS95

Katherine 12m

•Patrick need to swapped out the module due to bad disk, received an alarm error (m5-104 mk5cn: time-out, connection closed), tried to restart the mk5 in between scans but didn’t fix the error. The error is due to a faulty disk in the module (shows up in get_stats procedure), which causing writes to disk to be slower than usual. Have asked Mick to swap to a good module in the morning.

•Patrick received the following alarms (ALARM: error st -998 reading systemclock1, ALARM: error st -999 tcp/ip connection error, and WARNING: error st -10 ramp epoch time not -1 when preparing to load). Has checked antenna and it is in “operate” mode.

•Received WARNING: error st -5 error return from antenna and see mbus error. Have to halt and stow the antenna twice to fix it. In the morning a new module was swapped.

–Mk5 was responding. Mick swapped the module. Can continue to observe–
