L1-Power
Power Power may not techincally be consider part of “Layer 1” but it is a cirtial and often over look part of IT. Below I will go over the basics of power and then go into how it applies to IT. Voltage (V) Electromotive Force or often refered to as electric pressure. Common House voltage (in the US) is 120V but many higher end servers and UPS’s run on 240V. Amps (A) Amps are a measure of the flow of power, ushally you can think the thicker the cable the more AMPs (or electric flow) it can handel. (Again the plumbing ) Watts (W) The unit for Power is Watts, and watt is the combination for Voltage and Amperage. (W=V * A) Power Supplies are desigged to work at certiain voltages and amperage. It is alway important to check the type of power circuits you have and the power supply you are about to order. Connectors NEMA / IOS ...
