HYBRID KEY SYSTEM

7. Before Power Up

During the initial installation, it is best to verify proper system operation before plugging in any
amphenol-type cables to the MDF.
1. If you have already plugged the cables in, unplug them.
2. Verify that the AC voltage at the dedicated electric outlet is in a valid range.
3. Make sure the AC power switch is in the OFF position and the memory back-up switch
is ON.
4. Plug the KSU power cord into the dedicated polarised AC outlet.
5. Turn the AC power switch to the ON position. Then verify the status of the
'POWER', 'MONITOR' and 'IDLE' LEDs on the cover of the KSU.
Steady lighting of the 'POWER' LED indicates the presence of power, and a blinking 'MONITOR'
LED indicates that the main processor is functioning.
Steady lighting of the 'IDLE' LED indicates that the system is not in use.
If the 'POWER' LED fails to light, 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 light, you must correct the problem
before continuing. To do this:
1. Turn off the power switch.
2. Unplug all expansion cards except the base board.
3. Turn the system on and 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 the power supply or base board.
This should solve the problem. If it does not, contact your dealer for advice.
