Power Down Considerations - HP D7171A - NetServer - LPr Manual

Chapter 2
5. If an HP Console Switch is present, it must be on before the server is
turned on. Otherwise the server will not detect all the required
components, and will likely report an error.
6. Lastly, power on one server at a time, waiting for fan units to spin up
before powering on the next (if more than one is present in the rack).

Power Down Considerations

To power off the equipment, ensure that the network has been properly warned.
If possible, the network operating system should be in a known state prior to
powering off the server. You may want to power off servers before powering off
mass storage units and peripherals, though no specific order is necessary when
powering off rack-optimized servers and associated components.
