 After connecting the power supply to Compact ICE and turning it on, the "power" LED next to the connector will either turn, or begin flashing green. If a solid green light is present, this indicates that Compact ICE is powered on and ready to receive commands. If the light is flashing, Compact ICE is receiving power, but is not yet powered on and must be activated using the ''#PowerOn'' API command. The setting which controls whether Compact ICE boots immediately (Auto Turn On) can be configured via the ''#AutoPower <True/False>'' serial command, where <> denotes an argument and should not be included in the actual command . ''#AutoPower True'' will cause Compact ICE to boot immediately after receiving power from the power supply, giving the solid green light upon activation.
-If using the GUI, it is necessary to turn Compact ICE on with the "Turn Power On" button that appears next to the "Connect" button after connecting.

 ====Temperature Control====
-After powering up Compact ICE and setting up the terminal for sending commands, the first thing to do is temperature control all components of the system. Temp controls are found on board 4, and there are 4 channels which can be controlled. Channel 2 controls the temperature of the HAL package (the case), Channel 3 controls the temperature of the Master Laser, Channel 4 controls the temperature of the Follower Laser, and Channel 5 controls the temperature of the Vapor Cell with the atomic reference. Channel 1 is left open for control of an external SOA through the SOA TEC connector.

-The temperatures of all components are preset on shipment. In case the temperature drifts, it is possible to set the temperature of each channel with the ''TEMPSET <ch> <temp>'' command, where "<ch>" is the channel you wish to set the temperature of, and <temp> is a floating point temperature. To check the temperature of a channel, use the ''TEMPSET? <ch>'' command. Always check the temperature setpoint of a channel before turning it on. To enable the temperature servo on a channel, send the ''SERVO <ch> <ON/OFF>'' command. Do this for all channels after checking their setpoint temperature. It is imperative that the temperature servos be enabled before current is sent to the lasers. The ''TERROR? <ch>'' command can be used to monitor the progress of the temperature servo. It will display the difference between the setpoint temperature and the measured actual temperature of the channel in mK. This value reaches a maximum at 0.264mK and a minimum at -0.261
