PC Board Replacements

The replaceable printed circuit boards include the SBC/Alarm Transition board, the
McTi boards and the Power Supply board which are illustrated in the diagram below.
Most board jumpers are factory-set and should not require any change by the
customer. Refer to Section 1.1 for information about jumpers. Follow these steps
when replacing PC boards:
SAFETY PRECAUTIONS: McIAS 1610 uses plug-in modules with circuit components
1. Turn the power switch located on the Power Supply board to OFF.
2. Loosen the fastening screws and then remove the board, pulling the two end
tabs (pull straight out) and replace the board with a known good one (with
proper jumpers installed).
NOTE: Take extreme care when removing and inserting the processor boards.
There are components mounted on both sides of the boards. Do not let these
components brush against anything, especially the edge of an adjacent board
or panel.
3. Return power switch to "ON". McIAS 1610 will initialize.
McIAS 1610/IP NOTE: OAM&P allows the replacement (hot swap) of one McTi-24
board with another by powering down only the McTi board and not the entire system.
Refer to the McIAS 16xx/IP System Operation Manual, Section 3.2 for more
information.
