2.8 Power-Up Sequence
During the AlphaServer 1000 power-up sequence, the power supplies are
stabilized and the system is initialized and tested through the firmware power-on
self-tests.
The power-up sequence includes the following:
• Power supply power-up:
– AC power-up
– DC power-up
• Two sets of power-on diagnostics:
– Serial ROM diagnostics
– Console firmware-based diagnostics
Caution
The AlphaServer 1000 enclosure will not power up if the top cover is not
securely attached. Removing the top cover will cause the system to shut
down.
2.8.1 AC Power-Up Sequence
The following power-up sequence occurs when AC power is applied to the system
(system is plugged in) or when electricity is restored after a power outage:
1. The front end of the power supply begins operation and energizes.
2. The power supply then waits for the DC power to be enabled.
Note
The top cover and side panels must be securely installed. A safety
interlock prevents the system from being powered on with the cover and
panels removed.
