Below is the formula to calculate the max PoE port that can support by single switch
1. Max power consumption = 225W (For example: SMC6128PL2)
2. Switch consumption = 45W
3. PoE consumption = 180W (225W-45W)
4. PoE standard is 15.4W per port
5. 180W/15.4W = 11.8xx
Thus, the maximum port can support is 11 ports.
