How to Reboot the NEW TCS

Please read the two sections before pressing the RESET button! In the first case a controlled lowering of the mirror is made, in the second case it will fall down as the air is pressed out of the mirror bellows.
The reboot is made by just pressing the RESET button so it can be made also by an observer after clearance from a staff member if shown during the introduction.


... there is a 'light' TCS crash, UT is updating and the TCS is still guiding:


The ongoing exposure can be finished before TCS reboot. Note that dither steps (teloffset) wont work.

When the ongoing exposure has finished, abort any ongoing observing script with CNTR-C on the observing system.
TCS UIF: zenith and wait, pow-off and wait, kill y and wait until the message 'SendToSysLog: SysLog is no longer logging our logs.' appears on the TCS error device screen after about 30s or wait at least 1 minute.
Press the TCS Reboot button.
While the TCS is rebooting: shutdownobssys on the observing system.
Wait for TCS UI to start.
Find the accesscode with show-page 1 on TCS UI.
Restart the obssystems with new TCS accesscode.
While the obssystems are restarting:
- reset safety system with keys
- power-on y on TCS UI.
Once TCS power is on and the obssystem is running:
- setup-tel- on observing system.

... there is a 'hard' TCS crash, no update on UI and no reaction to keys, the TCS is not guiding:


The ongoing exposure has to be aborted and TCS rebooted asap.

Press the TCS Reboot button.
While the TCS is rebooting:
- Abort or readout the ongoing exposure (eg alfosc.abort or alfosc.readout).
- Then abort any ongoing observing script with CNTR-C.
- Shutdownobssys.
If the TCS is still rebooting, wait for it to start and then get the TCS new accesscode to appear with show-page 1 on TCS UI.
Restart the obssystems with new TCS accesscode.

While the obssystems are restarting:
- reset safety system with keys
- power-on y on TCS UI.
Once TCS power is on and the obssystem is running:
- setup-tel- on observing system.
