6.  Set the Mode Switch on the front of the DPU to “B” to demand a Cold 

startup. 

7.  Insert the DPU into the chassis slot but not far enough to make contact 

with the back plane connector. 

8.  Insert the ‘A’ Network cable into the top RJ45 connector and, if 

available, the ‘B’ Network cable into the second RJ45 connector. 

9.  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. 

10. Fully insert the DPU into the chassis slot and secure it using the two 

thumbscrews. 

11. Wait until the CP LED begins to blink Yellow/Green signifying that the 

DPU is operational.  

12.  Set the Mode Switch to ‘F’. 

13.  Once the DPU has ‘warmed’, the following are the expected states of the 

LEDs: 

• 

‘A’ Network – Green 

• 

‘B’ Network – Green if dual network and off if single network 

• 

Backup – Green 

• 

IOM – Green 

• 

I/O – Green if any Redundant I/O defined, Off if no Redundant I/O 

• 

CP – Blinking Green/Yellow 

• 

State – blinking Yellow/Off 

14.  Acknowledge all alarms from the new DPU and make sure they clear.  

Restarting a DPU after Failover 

If an inactive DPU detects a problem with the active DPU, it will 
immediately take control of the process and force the other DPU to become 
inactive.  If the originally active DPU is still operating, it will detect the loss 
of control and go into an offline mode, setting its State LED to red.  In this 
mode the DPU will not warm from the new active DPU until manual 
intervention.   

DO NOT reset the active DPU since there is no available backup and all the 
outputs will be reset.   Pressing the reset button on the inactive DPU will
