7. If an expansion cabinet is connected to the base cabinet, press the AC power
sequencer circuit breakers in the expansion cabinet to the On position.
Wait until the expansion cabinet completes its power up sequence and all array
component LEDs are in the green steady state.
8. At the bottom front and bottom back of the base cabinet, press the AC power
sequencer circuit breakers to the On position.
The three power status indicators on the front panel show the status of the front
power sequencer. The main AC power light emitting-diode (LED) is illuminated
when power is applied to the expansion cabinet. The LED for sequencer stage 1 is
illuminated next, followed by the LED for sequencer stage 2.
Note –
The front panel power sequencer bottom LED is illuminated only when the
AC power sequencer circuit breakers for the front power supply are on.
Note –
To check the status of the rear power sequencer, open the back door of the
expansion cabinet and look for the three green LEDs.
9. Wait approximately 1 minute after the AC power sequencer circuit breakers are
pressed on, and then, at the back of the system, locate the power switch for the
Storage Service Processor and press the switch off, then on.
All components of the system power on in an optimal state.
10. Verify that all the components have only green LEDs illuminated.
If LEDs other than green ones are illuminated, or if no LEDs are illuminated, see
“Troubleshooting Tips” on page 99 to troubleshoot any component that is not
powered on.
11. Replace the front trim panel and close the front and back doors.
The system is now powered up and operational.
