normally starts the booting process.

LED stops flashing and remains light. At this point the system had a default database.
8) The RUN LED of the board flashes when the power supply and processor status is
normal.

10) If the LED status of the MP20S or interface board is abnormal, turn off the power of the
cabinet and turn the power on again. If this does not restore normal system operation
contact Samsung Technical Support.

8.3 CHECKING THE FAN

When the system fan is not operating, the 48 DC power and the system operation will be
turned off to prevent system overheating.
This function is set in programming to send notification within 24 hours.
The function can be set using the following steps:
1) Use MMC 722 to assign a SYSALM key to designated keysets.
2) When FAN alarm is activated the SYSALM key will flash, the designated keyset will ring
and display message code MJA08.
3) Access MMC 851 to verify the alarm and MMC 852 to assign FAN ALARM to SYSALM key.
The MJA08 message means abnormal fan operation; therefore the system will be turned off
after 24 hours. When the alarm occurs, the fan must be replaced within 24 hours.
REMINDER
