Model PDP DPU Installation, Preparation and Adjustment
Demanding a Cold Startup
Starting a Standalone DPU
6-2
When a DPU is first placed in service, or when a DPU is moved from one
location to another, it is advisable to clear any previous configuration data
that may remain in its flash memory. To do this, before applying power to
the DPU, set front panel mode switches 1, 2, and 8 to the left, and mode
switch 4 to the right. After the DPU has gone through its startup sequence as
described in "Starting a Standalone DPU," be sure to set mode switch 4 back
to the left to prevent future Cold startups.
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 keylock to the Offline position (fully counter-clockwise).
2.
Insert a terminator (Part number 081388) in the backup link connector.
3.
On the backup DIP switch at the bottom of the DPU, set the top most
switch to the right (primary).
4.
Set front panel mode switches 1, 2, and 8 to the left, and set mode switch
4 to the right to demand a Cold startup, as described in the preceding
section.
5.
Verify that the NiCd battery pack is installed and plugged correctly into
P10 connector on the motherboard. Additionally, verify that protective
connectors (Part number 081389) are installed in the IOM and CPU load
connectors.
6.
Set the proper DPU Bus address in the station number switches.
7.
Position the module into the top and bottom card guides of the chassis.
8.
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.
9.
When the contacts are engaged and resistance is felt, firmly press on the
front panel of the module 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.
