PART 4. POWER UP PROCEDURES
4.1 CONNECT POWER TO THE SYSTEM
During the initial installation, it is best to verify proper system operation before plugging
in any amphenol-type cables to the MDF. If you have already plugged the cables in,
unplug them at this time.
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 RAM pack 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 on the power supply will light steady to confirm the presence of
power. If the PSU LED fails to illuminate, unplug the system, remove the power supply
and check the AC fuse located on the bottom.
If the fuse is good but the LED does not illuminate, you must correct the problem
before continuing. Turn off the power switch. Unplug all cards using the card ejectors.
Turn the system on. Check the LED again. If the problem is corrected, you have a
defective card. Test and remove the faulty card before continuing. If the LED still does
not light, 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 RAM CARD INDICATIONS
Having verified proper operation of the power supply, visually check the RAM 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 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.
4.3 PCB VERIFICATION
Before connecting all MDF cabling, plug in a test cable to the first DLI port. Connect a
display set and verify that it is working. Use maintenance program MMC 805 (or MMC
727 for Release 2 systems) to verify the system version, software version and that all
cards are recognized by the CPU. Remove the test cable and plug in all amphenol-type
cables to the MDF. Proceed with the rest of the installation.
