ADAM CS Front Panel Description
(Figure

, page
18
)
There are 10 card slots in the front panel. Starting from
the left side, slots 1 through 8 are for Audio Input/Output
Cards. Slots 9 and 10 are for main and backup Master
Controller Cards.
The two large bays at the right side of the front panel con-
tain main and backup power supplies. These power sup-
plies are mounted in shuttles which may be pulled out for
quick access/replacement. The power supplies are
designed for automatic switch-over in the event of a
power supply failure. There is an audible alarm for indica-
tion of power supply failure. An alarm override switch
lets the user turn off the audible alarm after notification,
allowing the affected power supply to be replaced at a
later time.

ADAM CS Back Panel Description
(Figure

, page

)
There are two fused AC power connectors with on/off
switches. The AC1 connector provides power to the PS1
power supply. The AC2 connector provides power to the
PS2 power supply.
Four AC-powered fans along the top of the back panel
provide cooling for the power supplies and circuit cards.
Either AC on/off switch will activate the cooling fans and
the associated power supply.
The bottom half of the back panel is reserved for the con-
nector panel. Three styles of connector panels are avail-
able, offering a choice of intercom port connectors:
RJ-11, 9-pin male D-sub, or 50-pin Telco. At the left side
of the connector panel are four additional connectors:
J900: DE-9S (female) connector for RS232 connection to
a personal computer.
J901: DE-9S connector for RS422/232 connection to an
RTS Trunking System.
J902: DE-9S connector for RS422/232 connection of
Program Assign Panels, LCP-102 Level Control Panels,
and UIO-256 Universal Input/Output Frames.
J903: DB-25S (female) connector for general purpose
interface. Provides eight, open-collector digital inputs and
eight relay outputs.

ADAM CS Frame Installation
The ADAM CS Frame is equipped with rubber feet for
placement on a desktop. For installation in an equipment
rack, it may be necessary to remove the feet. The frame
has no special ventilation requirements. Just make sure
that the ventilation holes on the front and back are not
obstructed. Allow space in back for attachment of connec-
tors.

Circuit Cards

Card Installation and Removal
Read This Before Installing Circuit Cards!
The connector pins on the back plane inside the ADAM
CS frame can be easily damaged by improper or hurried
insertion of circuit cards. Always use the following proce-
dure when installing cards.
1.
Insert the card edges into the upper and lower card
guides in the frame.
2.
SLOWLY push the card straight back into the slot
until initial resistance is felt.
3.
When initial resistance is felt, apply slightly more
pressure to begin engaging the connector pins.
4.
Once the connector pins have started to engage, press
VERY FIRMLY to completely seat the connectors.
When the card is properly seated, the card plate on
the front of the card should be flush with the front of
the ADAM CS frame, and the ejector levers on the
card plate should be in the horizontal position.
To remove a card, press down on the lower ejector lever
and up on the upper ejector lever. Once the card is
released from the back plane connector, pull it straight out
of the frame.
Cards should be secured in the frame at top and bottom
with the screws provided. Otherwise, vibration of the
frame could cause the cards to loosen over time.
Note
All ADAM CS circuit cards can be removed or installed
while the equipment is operating. This permits continuous
operation of the intercom system—with no interrup-
tions—in the event of any card failure.
