Power Up the Components in the Rack

Follow the Power Up Sequence to minimize initial surge currents and prevent
breakers from tripping.

Power Up Sequence

1. Ensure that the mass storage unit DIP switches are set for SCSI ID spin-
up order. See documentation included with the unit for more information.
2. Power on the tape back-up unit, if one is present.
3. Power on the mass storage units, one at a time.
4. Power on the monitor.
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.
No specific order is necessary when powering off rack-optimized servers and
associated components.
