Planning and Implementation for the E5400zl/E8200zl Switches
Configuration Examples
Figure 13-19.Example of a 5412zl with four power supplies (two J8712A and two J8713A)
In this example (Figure 13-19) there are two J8712A and two J8713A power
supplies supplying 2892 watts for PoE usage. With this configuration, 187 ports
(or more than 7 modules) can be provisioned at 15.4 watts, or all 288 ports can
be powered at 7.0 watts each.
Note HP ProCurve highly recommends that the two types of power supplies are not
mixed in the same 5412zl/8212zl chassis.
The reason the redundant # of ports in this table is so low is because redundant
PoE power should always be based on the smallest power supply. In this case
the smallest power supply is the 8712A providing 546 watts.
