Port card installation
Adding or replacing the port card will require the system to be taken out of
service. Wear a grounding strap and avoid unnecessary movement while
handling the circuit boards.
1. Unplug the power supply to IVX.
2. There are two card slots on the cabinet. The 360 expansion card is
ribbon-cabled to the main board.
Note: The first Amphenol connector (Port Card 1 slot) is provided by
the main board, which comes in a three-line, six-digital station,
two-analog port configuration.
3. Connect the port card (J1) in the base cabinet to the main board (J2)
via the ribbon cable that shipped with the port card.
4. Secure the port card to the standoffs with the screws that shipped with
the port card.
5. To remove the port card, reverse steps 1-4.
Memory Module
Note: The Memory Module has a proprietary formatting scheme — do not attempt to install a non-ESI
CompactFlash
®
. Contact ESI for a replacement Memory Module, if needed.
Adding or replacing the Memory Module will require that the system be powered down.
Replacing the Memory Module erases all its configuration data and custom recordings.
(Prompts stay intact, however.)
LED functions
The unit's various LEDs are designed to provide visual feedback as follows:
• Power LED — Located on the top-right side of the cabinet. Is illuminated when power is being
applied to the system. Blinks periodically to indicate that the main processor is operational.
• Port LEDs — Located above their respective amphenol connectors on the right side of the cabinet.
Each is illuminated when any port on its associated port card is in use.
Note: Disconnecting an amphenol connector when its respective LED is lit will cause any of its ports that
are in use to be disconnected.
Upon power-up, approximately one minute is required for the system to configure. The Power and Port
LEDs will blink three times to indicate that the power-up sequence has been completed.
• Memory Transfer LED — Located inside the cabinet in the center of the main board. Serves as a
diagnostic aid by flashing as data is transferred to and from the Memory Module.
