Connecting the Ground Wire (Figure 1-3)
1.After removing the front cover, loosen the lug on the
ground connection located on the lower right-hand side
of the cabinet.
2.Use a piece of 12 AWG stranded copper wire and connect
the wire to the ground terminal.  Tighten the lug on the
ground connector.
3.Connect the grounding cable to a known earth ground.

INSTALLING PCBs
Central Processing Unit (CPU) PCB (Figure 2-2)
Figure 2-2  CPU PCB
The CPU PCB comes already installed in the KSU. The
CPU provides:
lThe systemÕs central processing, stored program and
memory 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.
The batteryÕs life is between 3.5 and 7 years - depending
on how often the system is powered down. The more the
systemÕs...

INSTALLING PCBs
To prepare the CPU PCB:
1.Slide the INTswitch (SW1) to the left (toward INT).
This ensures that the system will load the default
database on initial power-up. Approximately 10 sec-
onds after initial power-up, you must change the
SW1 switch to the right.
Refer to Part 3, Installing Extensions and Trunksfor
instructions on connecting the stations and trunks.

INSTALLING PCBs
Note:  The Portrait 308 system can accommodate any
combination of optional cards, but the system
capacity can not exceed two optional cards.
To install a SMDRPCB:
1.  Align the 3SMDRPCB over the connector labeled
EXPCN on the CPU or other installed optional PCB.
2.  Press the PCB into the EXPCN connector.
3.  Using the two metal spacers included with the 3SMDR
PCB, attach the PCB to the CPU or other installed optional
card.
4.  Connect the RS-232C cable into the 3SMDR PCB.
5.  Locate the...
