Card Removal and Installation

All ADAM circuit cards can be "hot-installed", which means you do not have to turn the power OFF before installing or
removing a card. This permits continuous operation of the intercom system - with no interruptions to unaffected ports - in the
event of a card failure.
READ THIS BEFORE INSTALLING CIRCUIT CARDS!
The connector pins on the back plane inside the ADAM frame can be easily damaged by improper or hurried insertion of the
circuit cards. Always use the following procedure when inserting cards:
Begin installation with the back card. Orient the card so the edge connector is toward the bottom.
1.
Insert the card edges into the upper and lower guides in the back of the ADAM frame. Push the card in until the mounting
2.
plate is flush with the ADAM frame.
Install mounting screws in the top and bottom of the card plate to lock it in place.
3.
When installing a front card, orient it so the indicator LED and reset switch are at the top-front.
4.
Insert the card edges into the upper and lower card guides in the front of the ADAM frame.
5.
SLOWLY push the front card straight into the slot until initial resistance is felt.
6.
When initial resistance is felt, apply slightly more pressure to begin engaging the connector pins.
7.
Once the connector pins have started to engage, press FIRMLY to completely seat the connectors. When the card is
8.
properly seated, the card mounting plate should be flush with the ADAM frame.
Mount screws for the front cards are not required, but are recommended for mobile installations.
9.
To remove a front 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.
To remove a back card, first release the front card by pressing the ejector levers, then remove the back card.
IMPORTANT: All system clock signals are derived from the Audio Input/Output (AIO) Card in slot number 9, with clock
backup in slot number 8. Therefore, if your intercom system uses fewer than ten AIO Cards, make sure that slots 8 and 9 are
filled in any case. Also, never remove cards 8 and 9 at the same time as the intercom system will cease to operate.
NOTE: When a front or back audio card is removed, the displays on any keypanel connected to that card will display asterisks
instead of the normal key assignments. After a card is reinstalled, it may take a minute or two for the keypanel displays to
return to normal.

Unused Back Card Slots

To ensure proper air flow, each unused back card slot should be fitted with a card blank (p/n 9000-7467-003) to cover the
opening.

Master Controller Card DIP Switches

As shipped from the factory, all master controller card DIP switches are set to the default operation position. These settings
will be satisfactory for most applications. Optional settings are summarized in Table 1 on page 11 or Table 2 on page 12. If any
changes are made to the settings, make sure both the main and backup controller cards are set the same.

Power Supply Removal and Installation

Place the power switch on the front of the power supply in the OFF (O) position before removal. Loosen the two captive
thumbscrews on the front of the power supply, then grasp the screws to pull the power supply out.
