• Intercon-
nect Board
Check engine board connector CNMC for the fol-
lowing voltages:
CNMC-A1 = +5 V dc
CNMC-B16 = +5 V dc
If the voltages are correct, check the operator panel
cable condition and connection. If the voltages are
incorrect, disconnect all cables from the engine
board but leave the engine board connected to the
interconnect board. Measure the following voltages
again:
CNMC-A1 = +5 V dc
CNMC-B16 = +5 V dc
If the voltages are now correct, reconnect each
cable until the voltage is incorrect. Replace the
FRU causing the change in voltage.
If the voltage is still incorrect, replace the following
FRUs in the order shown:
1. LVPS
2. Interconnect board
3. HVPS
4. Engine board

Engine Fan
Be sure the engine fan turns on during POST. If it
does not, be sure the fan is connected properly.
Check the voltage on the engine board between
CNF2-1 and CNF2-2. If the voltage is +24 V dc,
replace the engine fan. If the voltage is incorrect,
replace the engine board.

• Engine
Board
Be sure the erase LED cable is correctly connected
to the CNERS connector on the engine board.
Disconnect the LED cable and check CNERS-1 on
the engine board for +24 V dc. If the voltage is
incorrect, replace the engine board. If the voltage is
correct, replace the erase LED.
