The very first thing to do when a new system has been assembled and is ready for testing is to perform a visual inspection. This critical step involves a thorough check of all components, connections, and the overall physical integrity of the system. Specifically, you should:

• Check all connections: Ensure all cables, wires, and connectors are properly seated and securely fastened. Loose connections can lead to intermittent failures or complete system malfunction.

• Inspect for damage: Look for any signs of physical damage, such as bent pins, cracked components, or loose screws. This includes looking for any signs of shipping damage that may have been missed during unpacking.

• Verify component placement: Make sure that all components are installed correctly, paying attention to the correct orientation and seating. Cross-reference with documentation if necessary.

• Ensure proper grounding: Verify that the system is properly grounded to prevent electrical hazards and ensure stable operation. A bad grounding may cause serious damages or not working at all.

• Look for foreign objects: Remove any foreign objects (e.g., stray screws, bits of wire, packing material) that could cause short circuits or other problems.

• **Check **Power Supply****: Make sure that power supply is proper and has the required voltage for system.

This initial visual inspection is crucial for identifying obvious problems before applying power, preventing potential damage or even safety hazards. It's a quick and relatively easy process that can save you a lot of time and trouble down the road.
