The internal power supplies are inserted in the back slots. These slots are labeled PS1 and PS2 on the 5406zl and PS1 through PS4 on the 5412zl. A power supply is
Power supplies
There are two different power supplies available for the HP ProCurve Switch 5400zl series. Both power supplies provide system power (the power needed to run the switch itself) and PoE power (the power sent down the Ethernet cable to power the device at the other end). The only difference between the two supplies is the amount of PoE power available from the supply.
All HP ProCurve Switch 5400zl series chassis use the same power supplies. There are two internal power supplies available:
•875W (110V/220V)
•1500W (220V)
As indicated in the following figure, the internal power supply provides both system power as well as PoE. The HP ProCurve Switch 5400zl series, as well as the 3500yl series, can power any device that adheres to the IEEE 802.1af standard. In addition, devices using
It is recommended that you use the same power supply model for all power supplies installed in a given 5400zl series chassis.

Figure 5. Power supply choices
The internal power supplies provide system power for all internal components (+12V output within +/- 5% tolerance, regulated) and power for PoE ports (-48V output within +/- 5% tolerance, regulated), which meets isolation and noise requirements of the IEEE 802.3af specification.
