 The HUT servers control functions such as beacon and dichroic movements, heater and dehumidifier usage, and various AO functions. An observer may find that the obsgtk is no longer controlling the beacon LED's, beacon flat or dichroic alignments. This happens on occasion with E2 and other scopes.  The HUT server may be the cause if it has quit or lost connection or the AOB may be at fault. To see if it is the server, open the HUT gui for the desired telescope from the CHARA menu. If the alignments can be changed from the gui, then the HUT server is ok. You can use the hut gui to continue observing.  If the hut gui gives move error messages, cycle the power on the AOB and open a new hut server to restore the connection to the obsgtk.  On the POWER gui, turn off the power to the AOB for the offending telescope and turn it back on.  Stop the hut server by logging into the appropriate telescope computer and identifying the PID with the bootlaunch_master command and killing the process with the kill -9 #### command.  Start the new server via the bootlaunch_master command.  Hit REOPEN on the obsgtk to reopen the connection to the HUT server and hit reopen on Cosmic Debris as well. The HUT servers control functions such as beacon and dichroic movements, heater and dehumidifier usage, and various AO functions.
