Attach one end of a PCDPM-to-DSS interface cable, part no. 813.1519, into connector
J2 on the PCDPM.
Remove the baseplate on the back of the DSS/BLF console.
On the connector board located in the baseplate, plug the free end of the PCDPM-to-
DSS interface cable, part no. 813.1519, into the main connector (J1).
Plug the AC transformer cable into the power connector (P1) on the baseplate connector
board. The transformer will later be plugged into an AC power source. DSS/BLF Units
always require their own separate AC transformers. For a diagram of AC transformer
requirements, see Figure 5-70 on
To attach a second 12-row DSS/BLF Unit to the first unit:
a. Plug one end of a DSS-to-DSS interface cable, part no. 813.1519, into the secondary
connector (J2) on the baseplate connector board in the first unit.
b. Remove the baseplate from the back of the second DSS/BLF Unit.
c. Plug the other end of the DSS-to-DSS interface cable into the main connector (J1)
on the baseplate connector board in the second unit.
d. Plug the AC transformer cable into the power connector (P1) on the baseplate
connector board in the second unit. The transformer will later be plugged into an AC
power source. If more than one 12-row DSS/BLF Unit is installed on an endpoint,
each unit must be equipped with an AC transformer. In addition, the PCDPM on the
corresponding endpoint must be equipped with an AC transformer.
To attach a third unit to the second unit, follow the same substeps outlined in
Perform the 12-row DSS/BLF Unit self-test:
a. While holding down the first two buttons in row one (extension numbers 1000 and
1001 in the default database), plug the main AC transformer into an available AC
power source. Do not use the outlet for the system chassis. Check that all of the
buttons light. If an LED does not light, unplug the AC transformer and plug it in while
holding down the first two buttons in row one (ext. 1000 and 1001). If the test fails
again, replace the DSS/BLF Unit.
b. Press each button individually (in any order) to remove the lit status. When finished,
check that all buttons are unlit. If an LED does not go out, unplug the AC transformer
and repeat steps a and b. If the test fails again, replace the DSS/BLF Unit. After all
buttons have been tested, it takes approximately five seconds for the DSS/BLF Unit
to return to normal operation.
c. Replace the baseplate on the back of the DSS/BLF Unit, taking care not to snag any
cables between the baseplate and housing.
