to the chapter on flashing the DPU).

20. Download the DPU using the maxDPUTOOLS program in the

maxSTATION.

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

clear.

22. Verify that the I/O LEDs that represent cards in your database and

I/O racks are now green.

Starting a Backup Pair of DPUs

When starting a backup pair of DPUs, it is recommended that you bring

the primary DPU up first and make sure it is running properly before

starting the secondary. Perform the following steps to ensure that an

unexpected failover does not occur during the startup process.

To start DPU backup pairs:

1. Turn the DPU key switch of both the primary and secondary DPU to

the Off-line position (fully counter-clockwise).

2. Set the front panel mode switch of both DPUs to “B” to demand a Cold

startup, as described in the preceding section if necessary.
