The used dss nodes are listed in the <hutch>.cnf file in the dss_nodes line. For XPP, if you have to take out the first dss_node in the list, you need to kill the source process running on that note, one way to do that is to use serverStat to reboot that node. This process will remain after the DAQ has been stopped and if you start a second one, weird things will happen.

To recover from that, you need to stop the DAQ process (ctrl+x in the telnet localhost 30099 terminal window) and open the Rayonix software capxure.
Reboot the detector controller (there is a button for that). Re-enable cooling. You might have to quite this process and start again to see the now reasonable temperatures. Once this looks fine, you can quit this software and restart the DAQ process: (ctrl+R in the telnet localhost 30099 terminal window)
"serverStat" at this moment works in all hutches when using the machine name or IP, but the "DAQ alias" interpretation feature might not quite work. We hope to improve on this soon.
