SAMSUNG DCS INSTALLATIONTECHNICAL MANUAL APRIL 1996PART 4. POWER UP PROCEDURES4.1 CONNECT POWER TO THE SYSTEMDuring the initial installation, it is best to verify proper system operation before plugging in anyamphenol-type cables to the MDF. If you have already plugged the cables in, unplug them.Verify that the AC voltage at the dedicated electric outlet is in the range of 220VAC. Make sure theAC power switch is in the OFF position and that the RAM pack battery switch is OFF. Plug the KSUpower cord into the dedicated polarized AC outlet. Turn the AC power switch to the ON position. TheLED on the power supply will light steady to confirm the presence of power. If the PSU LED fails toilluminate, unplug the system, remove the power supply and check the AC fuse located on thebottom.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 theLED again. If the problem is corrected, you have a defective card. Test and remove the faulty cardbefore continuing. If the LED still does not light, unplug the KSU and change power supplies. This inall probability will solve the problem. If it does not, contact Samsung Technical Support.4.2 RAM CARD INDICATIONSHaving verified proper operation of the power supply, visually check the RAM card indications. TheLED should flicker rapidly indicating the main processor is functioning. The battery switch shouldnow be turned ON.The system is equipped with a halt program.
