If a dome will not close after observing, it may need to be closed manually at the bunker. Turn the power to the dome off at the switch, disconnect the cable from the computer control box and connect it to the manual control switches above. Turn on the power to the dome after connecting the cable and use the two controls to close the dropout first, then the slit. The dropout must be fully closed and the slit closed over it to be shut properly. Inform the staff that the dome did not function properly so someone can look at it in the morning. | If a dome will not close after observing, it may need to be closed manually at the bunker.

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.

+ | If the server won't restart, a reboot of the power supply in the telescope bunker might be necessary. The power supply that controls the acquisition and finder cameras as well as their controllers is located on top of the computer rack in each bunker. The power supply has green readouts of volts and current. After turning the power off for 10 seconds and back on, try restarting the server from the computer in the bunker to see if it starts cleanly. If so, then restart the telescope server, reopen the connection to the telescope gui, and hit REOPEN on Cosmic Debris. Part of the HUT server also controls the AO table.
