8. BEFORE POWER UP

During 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. Verify that the AC voltage at the dedicated electric outlet is correct.

Make sure the AC power switch is in the OFF position and memory back-up switch is ON. Plug the KSU power cord into the dedicated polarized AC outlet. Turn the AC power switch to the ON position, and verify the status of the "POWER", "MONITOR", and "IDLE" LEDs on the cover of the KSU. A steady "POWER" LED indicates the presence of power, and a blinking "MONITOR" LED indicates that the main processor is functioning. A steady "IDLE" LED indicates that no one is using the system. If the "POWER" 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 "POWER" LED does not illuminate, you must correct the problem before continuing., Turn off the power switch., Unplug all expansion cards except Base board. Turn the system on. Check the "POWER" 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 or Base board. This in all probability will solve the problem. If it does not, contact Samsung Technical Support.
