PoE Calculation

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.

Stacking speed for SMC87xx & SMC88xx

The stacking cable speed is 12Gbps for uplink and another downlink speed is 12Gbps.

Apply on SMC87xx and SMC88xx
