Standard J8713A Configurations

Figure 4-11. Example of a 5412zl with two power supplies, J8713A

This configuration is an example of two power supplies supplying 900 watts

each for a maximum of 1800 watts to a fully loaded chassis of 288 ports.

Therefore out of the total 288 available ports, 116 can be powered at 15.4 watts

each. That’s equal to a little over 4 modules. Or all ports could be used at 4.0

watts.

Or, 55 ports could be provisioned at 15.4 watts using 847 watts of the total 1800

leaving 953 watts. Then provision the other 238 ports at 4 watts using 952 watts

of the remaining 953 watts. Finally leaving 1 watt.

This configuration could be redundant for PoE power up to 900 W. The upper

6 slots would stay up if they were the ports suppling the PoE power and the

lower 6 slots were used for other than PoE power. One power supply has

enough power to supply system power to the upper 6 slots and keep the switch

up and running. And as long as the 900 watts of PoE power is not exceeded,

then the top 6 modules would remain powered.
