4. To attach a second DSS/BLF Unit to the first unit:
a. Plug one end of a DSS-to-DSS interface cable 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 ( J4 ) on the baseplate connector
board in the second unit. The transformer will later be plugged into an AC power source. If
more than one DSS/BLF unit is installed on a phone, each unit must be equipped with an
AC transformer. In addition, if using PCDPM part number 550.3014 on the corresponding
phone, the PCDPM also must be equipped with an AC transformer. PCDPM part number
550.3018 does not require an AC transformer. For details, see “Connecting PCDPM Cables”
on page 1-357 .
5. To attach a third unit to the second unit, follow the same substeps outlined in step 4 .
6. Perform the following 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 unit into an available AC power source.
Do
not
use the outlet for the system chassis. Check that all 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, all
buttons should not be lit. 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 of the buttons have
been tested, it takes approximately 5 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.
Attaching a 12-Row DSS Unit
Install each 12-row DSS/BLF Unit as outlined following procedure. For diagrams of the installation,
see Figure 18 on
page 361
. A description of the units appears in “Direct Station Select/Busy Lamp
Field Units” on page 1-116 .
1. Attach one end of a PCDPM-to-DSS interface cable, part number 813.1519, into connector J2
on the PCDPM.
2. Remove the baseplate on the back of the DSS/BLF console.
3. On the connector board located in the baseplate, plug the free end of the PCDPM-to-DSS
interface cable, part number 813.1519, into the main connector ( J1 ).
4. 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
8 on
page 348
.
5. To attach a second 12-row DSS/BLF Unit to the first unit:
