AC Power Sequencer Control Panel: Power On
On the base cabinet, the Storage Service Processor, Storage Service Processor
accessory tray, network terminal concentrator (NTC), firewall/router, and Ethernet
hub will be powered up because they are connected to the unswitched power
outlets.
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.
All components of the system power on in an optimal state.
9. Verify that all the components have only green LEDs illuminated.
It takes several minutes for the diagnostics and initialization process to complete
and the LEDs to reach a steady state. If LEDs other than the green ones are
illuminated, or if LEDs are not illuminated, see “Troubleshooting Tips” on page 99 to
troubleshoot any component that is not powered on.
10. Replace the front trim panel and close the front and back cabinet doors.
