- **Phase**		:	2  
- **Status**		: 	[[span(style=color: green, **COMPLETE** )]]  	 
- **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.
- The functionality and operability of individual components/sub-systems are tested. Verification of the internal alignment of the instrument is performed using the light source within. The final step is the performance of the system.


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

**Procedure for Basic Functionality**
- 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.
- Testing the electronics and SW rotation of the knob controlling the cool down process (LBTI side).


**Procedure for Basic Functionality**
- Initialize all the motors/sub-systems.
- Check the functionality of all the motors (home position, named/nominal positions, and reaching software limits).
- Check the working of all the light sources.
- Using the on-axis diffraction-limited light source, check the internal alignment of the SHARK-NIR.
- Check the relative positions of the coronagraphic masks.
- Check for on-axis optical quality.

- SHARKNIR_cal_tec_NCPA_trial  (Trial & Error approach)
- SHARKNIR_di_mon_MaskRepeatability

**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.
- Motors and light sources are working as they should.
- The internal alignment is preserved.
- Performance of the system is acceptable.


**Notes**

**LBTO support**
- Testing the working of the knob (motor or manual) controlling the cooldown.
