- Top power supply LED begins flashing (green) and Bottom LED ON (solid
green)
- This is the indication that the power switch is on and the power supply is in a
power on delay mode
- No change in the IMD
•
When power-on delay is up, unit turns on
-
Top Power Supply LED will momentarily flash yellow then both LEDs should
stay green, Top power supply LED ON (solid green) and bottom LED on (solid
green)
- Power-On LED comes ON (on the front of the unit)
- IMD resets and then starts initialization sequence (refer to Appendix more
details on the IMD initialization sequence)
- All the fans begin spinning, (a green LED on each of the fan assemblies should
turn on)
•
After a few seconds, the fan controller will turn off the redundant fans (ones closest
to the front of the unit, 1 for each zone). Note that a turned off fan may still spin due
to the air being forced through it by the other fans. Typically the redundant fans
being turned off is most notable by the change in sound.
-
The green LED for each of the fans should remain ON (even the fans turned off
by the fan controller)
- Only if there is a fan failure should the green LED turn OFF and the red LED
turn ON
- The IMD will continue to display the initialization sequence progress
IMD (Integrated Management Display) or the LCD
1) The IMD is off (dark) unless AC power is applied to the power supply and the +5v AUX is on.
2) When it comes up, it displays:
COMPAQ LCD
MODEL # 56022
LCD FIRMWARE 1.9
3) When AC power is first applied and it comes up, the buttons have no effect on the display. The system
will have to be powered up first.
4) When the system is powered on, the IMD will start its initialization sequence. The LCD screen will be
cleared, it will display the model # and the LCD firmware revision and then the bottom line will have
“MAIN MENU”. The other 3 lines will begin displaying the intialization sequence:
Systen Init.
PCI Auto Cfg.
Video
Memory Test
Memory Init.
Floppy Drive
Option ROMs
SCSI Devices
F1 Prompt
5) A rotating line will appear by each of the above prompts to indicate that section of post is being
executed. When post completes that section, the rotating line will be replaced by a check mark.
6) If the display is not “messed” with, when the system is powered down, the display will indicate:
System Powered OFF
The above sequence is for a system with minimal hardware under normal operation.
