Fan Assembly - HP 7500 Series Installation Manual

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:
