Starting a Backup Pair of DPUs
When starting a backup pair of DPUs, it is preferred (but not required), to
bring the primary DPU up first and make sure it is running properly before
starting the secondary.
To start DPU backup pairs:
1. Remove the CompactFlash from the primary DPU and inset it into a
Reader/writer attached to a Workstation. Use the Workstation utility
DPU4FSetup program to initialize the CompactFlash. This utility will
configure the IP Address, Pair Mode (Select Primary), Network
Speed/Duplex, and Version of Software. Reinstall the CompactFlash in
the DPU. Repeat for the secondary (Select Secondary).
2. Set the Primary DPU Mode Switch to “B” to demand a Cold startup.
3. Insert the Primary DPU into the chassis slot but not far enough to make
contact with the back plane connector.
4. Insert the ‘A’ network cable into the top RJ45 connector and, if
available, the ‘B’ network cable into the second RJ45 connector.
5. Insert the ‘Backup’ network cable into the backup connector. NOTE: If
the DPU is restarted without the backup cable installed, the DPU will not
be permitted to go online. The DPU must be reset after the cable is
installed.
6. Fully insert the Primary DPU into the chassis slot and secure it using the
two thumbscrews.
7. Wait until the CP LED begins to blink Yellow/Green signifying that the
DPU is operational.
8. Set the Mode Switch to “F”.
9. Verify that the status LEDs on the DPU front panel are in the proper
state:
•
“A” Network - Green
•
“B” Network – Green if dual network and off if single network.
•
Backup – Off (will turn Yellow when Secondary operational,
Secondary LED will also be Yellow)
