Starting the DPU

22. It will take up to about a minute for a blank DPU to boot (if a DPU has a

large database, the boot time can be up to about 2 minutes).

23. Return the Mode switch to “F.”

24. Verify that the battery test passes (Battery LED is green.). This can take

up to about another minute.

25. Verify that the Net A and Net B LEDs are green.

26. Verify that the CP LED is blinking green/yellow.

27. Verify that the IOM LED is green.

28. Verify that four I/O LEDs are off (there is no database in the DPU).

29. Make sure the secondary starts up and begins communicating on the

maxNET.

30. Verify that the DPU shows up as healthy in the HealthLog list. This

time, both the Primary and Secondary should be seen as healthy.

31. Verify that the DPUs are running the proper versions of DPU firmware

(refer to the chapter on flashing the DPU).

32. Download the primary DPU using the maxDPUTOOLS program in the

maxSTATION.

33. Acknowledge all alarms from the DPU and make sure that they all clear.

34. Verify that the Primary’s I/O LEDs that represent cards in your database

and I/O racks are now green.

35. Run the DLFreezeCheck program, on the maxSTATION, to unfreeze the

outputs and allow all or selective outputs to go to their new computed

values.

36. Place the primary DPU’s key switch in the Run or Locked mode.

37. The State LED and Backup LEDs will blink various color combinations

as the primary DPU recognizes the presence of the secondary DPU and

warms it up (transfers the database and data values). The LED color

sequence is described in a previous chapter.

38. When the warming process has completed and the backup becomes hot,

the Primary’s State LED will blink green/yellow and its Backup LED

will be green. The Secondary’s State LED will blink yellow/off and its

Backup LED will be green.

39. Assuming that this DPU pair does not have redundant I/O modules, the

I/O LEDs on the inactive DPU will be off.
