iDCS 100
INSTALLATION
TECHNICAL MANUAL
PART 4 JUNE 2002
4.1
PART 4. POWER UP PROCEDURES
4.1 CONNECT POWER TO THE SYSTEM
Verify that the AC voltage at the dedicated electrical outlet is in the range of 82–132
Volts AC. Make sure the AC power switch on the system power supply is in the OFF
position and that the SMEM card battery switch is also in the OFF position. Plug the
KSU power cord into the dedicated polarized AC outlet. Turn the AC power switch to
the ON position. The LED’s on the power supply will light steady to confirm the
presence of power. If both PSU LEDs fail to illuminate, unplug the system, remove the
power supply cover and check the AC fuses located on the left-hand side of the face of
the PSU.
If the AC fuses are good but the AC LED does not illuminate, unplug the KSU and
change power supplies. This in all probability will solve the problem. If it does not,
contact Samsung Technical Support.
If the AC LED is illuminated but the DC LED is out you must correct the problem before
continuing. Turn off the power switch and check the DC fuses located in the opening of
the face of the PSU. If the DC fuses are good but the DC LED does not illuminate,
unplug the PSU from the motherboard. Turn the system on. Check the LEDs again. If
the problem is corrected, you have a defective KSU motherboard or card. Test and
remove the faulty card before continuing. If this does not correct the problem, unplug
the KSU and change power supplies. This in all probability will solve the problem. If it
does not, contact Samsung Technical Support.
4.2 iDCS MEM3 CARD INDICATIONS
Having verified proper operation of the power supply, visually check the iDCS MEM3
card indications. The LED should flicker rapidly indicating the main processor is
functioning. The battery switch should now be turned ON. If the LED remains lit steady
turn power to the system OFF remove the iDCS MEM3 card and check the installation
of the EPROM’s by removing them and checking for bent or damaged pins. If the
EPROMs appear to be installed correctly and the system does not come up when
turned on, contact Samsung Technical Support.
The system is equipped with a halt program. When this program is running, the LED is
ON steady. The system must be reset to release the halt program and restore the
system to normal operation
(see MMC 810 for operation of the halt program)
