Planning and Implementation for the HP 5400R zl2 Switches
Configuration Examples
This configuration could be redundant for PoE power up to 900 W. The upper
6 slots would stay up if they were the ports supplying 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.
This configuration (Figure 14-12) is an example of three power supplies
supplying 900 watts each for a maximum of 2496[(92.5*(900*3)]watts to a fully-
loaded HP 5412R zl2 Switch with 288 ports. Therefore out of the total 288
available ports, 161 can be powered at 15.4 watts each.
