hi -
thanks for the message....
after power is restored, the tofp systems all come up in a safe state.
i.e. the daq computer reboots into the mini-system, and all
nps plugs (except for the plug for this PC) will come up in the off state.
see:
http://mac8.rice.edu/~TOF/TOFp/operations/tofp_shiftcrewFYI.html
there is a recovery procedure linked there.
these steps should restore the systems needed to interact w/ star
and take data.
some things like the cron job that polls the caen for the 1/minute
tofr hv monitoring may or may not revive automatically so these
things have to be checked once the rest of the systems are up again...
let me know if you want me to just power it all up from here....
