INSTALLING PCBs
Central Processing Unit (CPU) PCB (Figure 2-2)
Figure 2-2  CPU PCB
The CPU PCB comes already installed in the Main Cabinet.
The CPU provides:
lThe systemÕs central processing, stored program and mem-
ory for the customerÕs site-specific data.
lMode switch for cold (default data) or warm (customer
data) start on power-up.
lBattery for backup of the customerÕs site-specific data. Use
only a SONYCR2032 Lithium Battery or equivalent.
Replace the battery when ÒBÓ flashes on the display of the
key telephones.  The batteryÕs life is between 3.5 and 7
years - depending on how often the system is powered
down. The more the systemÕs power is off, the shorter the
batteryÕs life.
lConnection points for the CO and station DDK connectors.

							INSTALLING PCBs
To prepare the CPU PCB:
1.Slide the Switch-1 (top switch) to the INT(left) position.
This ensures that the system will load the default data-
base on initial power-up.
2.Power the system up.
3.  After the system has been powered up for a minimum of
10 seconds, insert the battery into the battery clips.
The printing on the battery should be facing up so that
it is visible when installed.
4.  Slide the Switch-1 (top) to the RUNposition (to the right).
Note:NEVER move the switch unless the intent is to clear
all programmed memory.
Refer to Part 4, Installing Optional Equipmentfor instruc-
tions on installing Background Music and Music on Hold.

Expansion (2CO/8STA) PCB (Figure 2-3)
Figure 2-3  EXPANSION (2CO/8STA) PCB
The Expansion (2CO/8STA) PCB provides DDK connectors
for two additional CO lines and eight additional telephones. 
To install a 2CO/8STAPCB:
1.Place the 2CO/8STAPCB on top of the CPU. Align the
EXPCNfemale connector on the bottom of the 2CO/8STA
PCB over the EXPCN male connector on the PCB below.
Push down firmly on the expansion PCB to ensure that the
EXPCN connectors are firmly together. Using the addi-
tional spacers included with the 2CO/8STAPCB, attach
the PCB to the card below.
2.Connect the green earth ground lead terminal to the ETH
screw on the CPU. An earth ground is alwaysrequired.
3.Refer to Part 3: Installing Extensions and Trunksfor
cabling instructions.
4.  If installing a second Expansion PCB, simply place the
card over the first PCB and repeat steps 1-3.
5.  To install an Expansion PCB if an SMDR or Power Failure
PCB has been previously installed:
lPower down the system
lRemove the SMDR and/or Power Failure PCB
lInstall the Expansion PCB
lReinstall the SMDR and/or Power Failure PCBs
lPower up the system.

Ring Generator PCB (Figure 2-4)
Figure 2-4  RING GENERATOR PCB
The Ring Generator PCB provides the ring generator source
when connecting a single line telephone, modem, voice mail,
or answering machine as a system extension. This must be
installed when any single line telephones are used in the sys-
tem.
To install a Ring GeneratorPCB:
1.Align the PCB on the left side of the Main Cabinet, below
the power switch.  Using the three screws provided, attach
the PCB to the Main Cabinet.
2.Attach the cable from the Ring Generator PCB to the con-
nector labeled RGUCN mounted on the CPU.

Auxiliary PCB (Figure 2-5)
Figure 2-5  AUXILIARY PCB
The Auxiliary PCB provides:
l2-pin DDK connectors for two External Paging Zones.
l2-pin DDK connectors for two Door Boxes.
l2-pin DDK connectors for two common-use relay contacts.
l2-pin DDK connectors for Background Music source.
l2-pin DDK connectors for Music On Hold source.
To install an Auxiliary PCB:
1.Insert the two card holders (included with the PCB) into
the outer holes on the right-hand side of the Main Cabinet.
2.Insert the Auxiliary PCB into the card holders.
3.Connect the ribbon cable (included with the PCB) to the
Auxiliary PCB and then to the DHUCN connector on the
CPU.
4.Refer to Part 4: Installing Optional Equipmentfor more
on installing Door Boxes, External Paging Equipment and
Alarm Sensors.

Power Failure (4 PF XFER) PCB (Figure 2-6)
Figure 2-6  POWER FAILURE (4 PF XFER) PCB
The Power Failure (4 PF XFER) PCB provides DDK connec-
tors for four power failure cut through circuits to four single
line telephones.
To install a 4 PFXFER PCB:
1.Place the two nylon spacers included with the 4 PF XFER
PCB in the lower holes in the middle of the CPU (or
2CO/8STAPCB, if installed).
2.Align the 4 PF XFER PCB over the metal and nylon spac-
ers.
3.Using the two metal spacers included with the 4 PFXFER
PCB, attach the PCB to the lower PCB.
4.Refer to Part 4: Installing Optional Equipmentfor more
on installing Power Failure telephones.

INSTALLING PCBs
SMDR PCB (Figure 2-7)
Figure 2-7  SMDR PCB
The SMDR (Station Message Detail Recording) PCB pro-
vides a record of the systemÕs outside calls. Typically, the
record outputs to a customer-provided printer, terminal or
SMDR data collection device. Use SMDR when you need to
monitor the usage at each extension and trunk.
To install a SMDR PCB:
1.Place the two nylon spacers included with the SMDR PCB
in the upper holes in the middle of the CPU (or 2CO/8STA
PCB, if installed).
2.Align the SMDR PCB over the nylon spacers. Press the
PCB into the connector labeled EXPCN on the CPU or
2CO/8STAPCB.
3.Connect the SMDRjack and cable assembly to the Main
Cabinet base. Insert the other end of the cable into the
RSCN connector on the SMDRPCB.
4.Using an RS-232C cable (Figure 2-8), plug the printer into
the SMDR jack assembly. Set the interface conditions of
the printer as follows:
Word length:7 bits
Parity bit:Even parity
Stop bit length:2 bits

SMDR RS-232C Cable Assembly (Figure 2-8)
To connect the SMDR and printer, an RS-232C cable is required.
If you make your own cable, it must be a straight-through cable
connecting pins 2, 3, 6, 7, 8 and 20.  Refer to the Figure 2-8.
Note that the cable length should not exceed 50Õin length.
