CHAPTER 5 TROUBLESHOOTING
Symptom
Beep codes
5 beeps at startup (2 beeps
followed a few seconds
later by 3 more beeps)
Any other multi-beep pattern may indicate a hardware failure on the
motherboard. Before replacing any components, first check the items in
T05-102-01 to 5, "Verifying the system," on page 5-5 to 5-9.
Startup
iR-M2 does not start up,
or the Control Panel is not
backlit.
T05-104-01 iR-M2 error messages and conditions (Continued)
5-12
Possible cause
The first two beeps indicate
that the CMOS settings were
lost due to a dead battery.
The three beeps that follow
indicate that the system has
restored the settings during
startup.
The iR-M2 is powered off.
Possibly one of the follow-
ing:
• Faulty power supply
(power supply may not be
supplying power to the
motherboard)
• Faulty motherboard
(motherboard power plane
may not be supplying
power to components)
• Faulty user interface board

Suggested action
You may have to replace the motherboard
battery.
Make sure the power switch on the back
of the iR-M2 is in the on position.
1. Check again all cables and connec-
tions.
2. Check power to the CD-ROM drive.
If the LEDs are lit during startup and
you are able to eject the CD-ROM
drive tray, then the drives are receiv-
ing power from the power supply.
3. Listen for the power supply fan and
feel for air at the back of the unit
where the power supply is located.
If you do not feel air from the power
supply fan and the drives are not re-
ceiving power, you may have a faulty
power supply which you will need to
replace (see page 4-41).
4. Check the fan vent on the back panel
to make sure air is coming out the
back of the system.
If the air is not coming out the back
and the drives are not receiving
power, the motherboard is faulty and
the motherboard will need to be re-
placed (see page 4-26).
5. If you have verified that the power
supply and the motherboard are func-
tioning properly, you may need to
replace the front panel containing the
user interface board (see page 4-7).
