Planning and Implementation for the HP 5400R zl2 Switches
Configuration Examples
In this example (Figure 14-6), there is one J9828A and one J9829A power
supply supplying 1086 watts for PoE usage. This configuration offers 142 ports
of which all can be powered at 7.5 watts each, and offers two ports for fiber
optic gigabit connectivity.

The following table shows the label and description of HP 5406R zl2 with two
power supplies, J9828A and J9829A:
Note Redundancy is not allowed for unlike power supplies.
One power supply (J9828A) could be used to supply PoE power at 275 watts
and the other power supply (J9829A) could be used as a secondary power
supply. If both power supplies are connected to different power sources, one
could backup the other in case of failure. However, if the J9829A power supply
