NOTE:
The rack unit (RU) specifies the rack height, and 1 RU is 44.45 mm (1.75 inch).
• Make sure the total maximum output power of the ordered power supplies is greater than the overall
power consumption. HP recommends that you reserve 20% of the maximum output power.
• If the switch is expected to supply power for attached devices through PoE, order a power supply
that can be used for setting up a PoE system depending on the switch model, and make sure the
maximum PoE output power of the power supply is greater than the PoE power consumption.
NOTE:
• For more information about installing power supplies, see "Installing FRUs."

or more information about the overall power consumption and PoE power consumption, see
"Appendix A Chassis views and technical specifications."
