OTE
:
If the Activity light
is solid orange while the
control panel is black, the
E-42 is in Sleep Mode.
Possibly one of the following:
• The E-42 is powered off
• Power cable is not plugged into
the power connector on the E-42
connector panel, or into the wall power
outlet
• The connector panel power switch is in
the OFF position
• UIB cable is not connected to
the motherboard, the user
interface board, or both
• Faulty power cable
• Faulty power supply (power supply
may not be supplying power to
the motherboard)
• The CMOS jumper is not in the
default position
• Faulty motherboard (motherboard
power plane may not be supplying
power to components)
1 Recheck all cables and connections.
2 Make sure the connector panel power switch is in the ON
position (see
).
3 Listen for the power supply fan and feel for air at the back
of the unit where the power supply is located.
If air is not coming from the power supply fan, isolate a
possible faulty power cable as follows:
• Power on using a different power cable.
• Install a new or “known good” power supply.
4 Check the connector panel fan vent and feel for air coming
out of the back of the system.
If air is coming out of the power supply fan vent but is not
coming out of the connector panel fan vent, the
motherboard may be faulty. You may need to replace
the motherboard (see
).
5 Review the jumper section on
and ensure that the
jumper is in the default position, then clear the CMOS
(see
).
Activity light status:
Off.
