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...

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...

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-...

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....

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...

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...

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 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.

POWERING UPTHE SYSTEM
Power-Up Sequence
Now that all the PCBs you need are installed, you can power-
up the system.
1.Install a surge protector in the AC outlet you intend to use
for system power.
2.Plug the AC power cord for the Main Cabinet into its surge
protector.
