FIGURE 7-5 CONNECTING EXTERNAL BATTERY
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.
