== P2.1	Basic functionality and shutdown procedure test, cryostat cooldown == 

- **Phase**		:	2  
- **Status**		: 	Draft	 
- **Category**	:	Daytime testing (functionality and operability) (C3)				
- **Recurrence**	: 	once after instrument installation at telescope platform
- **Duration**	: 	1 day

**Description**
- Activating the instrument after the installation of SHARK-NIR at the telescope platform. Verification of the shutdown procedure.

**Prerequisites**
- SHARK-NIR is installed on the LBT telescope platform.

**Procedure**
- Switch on all the cabinets, follow the instrument telemetry and see if the telemetry is logging.
- Turn all the hardware subsystems turned on and start all the corresponding services. Check all the logs from the services.
- Check the shutdown procedure (except the cryostat warm-up).
- Testing the electronics and SW rotation of the knob controlling the cool down process (LBTI side).
- Cooldown the cryostat.

**Templates**

**Success criteria**
- Activating instrument successfully.
- All systems are turned on, and the services are all running without any errors.
- The shutdown procedure is checked and working as it should be.
- Cryostat cooling started and is on track.

**Notes**

**LBTO support**
- Testing the working of the knob (motor or manual) controlling the cooldown.
- Liquid Nitrogen fill
- Vacuum pump
