It is also possible for the DPU to automatically clear its database. When the

DPU starts up, it reads its IP address from the switches on the chassis panel.

If the DPU has a database, it compares the switch address with the address in

its database. If they are different, the DPU will clear its database. This is a

safety measure that is intended to prevent incorrect control operation that

might otherwise be caused by installing a loaded DPU in the wrong chassis.

Starting a Standalone DPU

Perform the following steps to ensure that a DPU is completely configured

before it is allowed to assume control. It is important that the DPU not be

placed in the Online state until it has been fully configured.

To start a standalone DPU:

1. Turn the DPU key switch to the Off-line position (fully

counter-clockwise).

2. Set the front panel mode switch to “B” to demand a Cold startup, as

described in the preceding section if necessary.

3. Verify that the NiCd battery pack is plugged in to connector J13 on the

DPU (refer to the chapter on battery and fuse maintenance).

4. Verify the proper IP Address is set in the Network Address switches.

5. Position the DPU into the top and bottom card guides of the chassis but

do not push it in all of the way.

6. Carefully slide the module forward, verifying that the connector pins on

the solder side of the module engage the corresponding contact guides on

the chassis assembly.

7. When the contacts are engaged and resistance is felt, firmly press on the

front panel of the DPU’s front plate to make the simultaneous

connections at the front and rear. Apply pressure to the left of the LEDs

to place the force directly in line with the printed circuit card of the

module.

8. Secure the module to the chassis assembly with the top and bottom lock

down screws on the front of the module.

9. 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).

10. Return the Mode switch to “F.”

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

take up to about another minute.
