Goals
When would a 6C207-3 power supply be necessary?
Why does a 6C207-3 require two power inputs?
Solution
In a Matrix E7 (6C107) chassis, these are the AC power supply requirements:
The 6C207-3 power supply (one or two) is the only option for powering a 7C107 (Matrix N7) chassis.
A fully loaded 6C207-3 power supply draws 22 amps at 120 volts - more than a 20-amp circuit would be able to provide. Given the logistics necessary to provide a 30A (30-amp) circuit, a dual-input design was deemed to be more sensible. In order to activate a 6C207-3 power supply, both inputs need to be connected.
On 120-volt power systems, for each power supply one of the two cables draws up to 10A and the other draws up to 12A, for a total potential draw of 22A. The cables provided for this purpose have a maximum rating of 20A. To prevent overdrawing the circuit and blowing the circuit breaker, each input needs to be connected to at least a dedicated 120V 15A circuit breaker - for a total of four separate 15A circuit breakers servicing a single chassis. You may alternately opt to use two 30A circuit breakers, or one 30A and two 15A circuit breakers.
On 240-volt power systems, this same argument would apply but with half the amperage for the same current draw (Volts x Amps = Watts). The cables provided for this purpose have a maximum rating of 10A, with an anticipated 6A maximum draw. Four separate 240V 10A circuit breakers servicing a single chassis would generally be necessary. However, if 240V 30A circuits are available, then all four inputs can be connected to the same circuit breaker without overloading it - but the best setup is always a separate circuit breaker for each input, for redundancy purposes.
For use in North America, power cable part# 5601313-U1 (included) terminates in IEC C13 and NEMA 5-15P plugs, compatible with a 6C207-3 and a NEMA 5-15R or 5-20R 120-volt receptacle.
For use in North America, power cable part# 5601013-U2 (purchased separately) terminates in IEC C13 and NEMA 6-15P plugs, compatible with a 6C207-3 and a NEMA 6-15R or 6-20R 240-volt receptacle.
For use outside North America, the correct power cables for the install location are included with each 6C207-3 purchased.

Solution
In a Matrix E7 (6C107) chassis, these are the AC power supply requirements:
- With any combination of 1st/2nd/3rd Generation switches and/or not exceeding five Matrix N-Series DFEs present, one 6C207-1 (1200 watt) power supply will provide sufficient non-redundant power. See 5181 for more.
- With any combination of 1st/2nd/3rd Generation switches and/or any number of Matrix N-Series DFEs present, one 6C207-3 (1600 Watt) power supply will provide sufficient non-redundant power. See 5181 for more.
