Access Panel Interface
General Information
This data sheet applies to the Model 69257-101 Access Panel Interface (API), which allows up to eight
access panels to be interfaced to a SmartSeries system. It is installed in a 10457 Series Card Rack and is
controlled by a 69254 Series or 69440 Series Master Control Unit (MCU) installed in that same card rack.
The API is designed exclusively for use in a SmartSeries system, and is not intended for use with other
types of equipment.
The following table describes the API front panel LEDs and their functions:
LED Status Description
ON LINE On The MCU is running and is configured to recognize the API.
Off The API is not receiving power from the card rack or the MCU is not properly
configured to recognize the API.
FAULT On The MCU has detected at least one failure in any of the access panels attached
to the API.
Off The “On” condition is not occurring.
Connections to the API are typically accessed via one 26-pin terminal block module mounted inside the
system’s control cabinet. A ribbon cable connects the terminal block module to the rear of the card rack
housing the API card. The terminal block module connects to the top connector associated with the API;
the bottom connector is unused.
Changing to a 69257-101 API from a previous version
1. The 69257-101 API is not electrically compatible with its predecessors. If further information on the
differences is needed, please contact the GAI-Tronics Field Service Department at 800-492-1212.
2. When upgrading to a 69257-101 API, the following four upgrades are required:
• Any 69266-001 or 69320-001 VNAs must be upgraded to the 69320-101 VNA.
• Any 69257-003, 69257-002, or 69257-001 APIs must be upgraded to the 69257-101 API.
• Any 69510-001, 69215-003, 69215-002, or 69215-001 backplane termination boards must be
upgraded to the 69510-101 Termination board. Two of these boards are required per card rack.
• The upgraded cards must be installed in the proper backplane slot. This task involves moving the
card and the associated ribbon cable at the rear of the card rack assembly.
