Chapter 1: Troubleshooting Tips for
8230 XRA1/2/3 Systems
1) The MaxPac8230 has both a hard power switch (at power supply itself ---O; --- for ON) and a soft power
momentary switch (on center monitor behind the display controls). If the optional UPS Power
Management System is installed and the 8230 is ON then removing the AC chord or switching the hard
power to O will not shut down the system. Instead the UPS system will beep and provide power through
the batteries. The system must be shut down via Windows or the soft power switch for a complete
shutdown to occur. Failing to do this step when packing up your system will drain your batteries.
2) When AC power is applied to the 8230 the motherboard goes into standby power mode. Some of the
motherboard circuitry is powered waiting on the soft power or other low level command. When the
motherboard first goes into standby (AC power applied with hard power switch ON) the 3 keyboard led’s
will flash green and then turn back off.
3) When the 8230 is powered on via soft power all of the display power LEDs should turn on with an orange
color. During initial startup the primary display will not light-up until a good portion of the POST (Power On
Self Test) sequence is complete. This time delay depends on the amount of memory present but for most
systems is about 10 seconds. Then all 3 of the keyboard LED’s should flash green. Usually the left
keyboard LED will remain lit. If you need to get into the motherboard BIOS depress the Delete key a few
times now. The BIOS will not be entered until initialization is complete including scanning of drives
attached to the RAID controller.
4) At this stage if any of the display LEDs are RED (instead of Orange or Green) then the display is off.
Depress the display power button (next to the display LED) to power up the display. It’s LED will change
from Red to Orange to Green and back to Orange if the display is not receiving a signal. The LED should
stay green if receiving video signals. Also note that each display must have its input set to DVI and NOT
RGB. To change the input source use the Input button on the display. The RGB input can be used if one
of the display’s PIP VGA inputs is connected from an external source (discussed later) and you wish to
display it’s data rather than the 8230 video data. Initial BIOS initialization data only will appear on the
Primary PCI Express graphics board’s displays. This is normally the Center and Right screens. The Left
screen (if present) will show “No signal DVI” until it has been enabled in Windows. Note that the power
state, input mode, etc of each display is saved for subsequent power-up cycles.
5) At this point depressing the Num Lock key (upper left of the numeric keypad) repeatedly will toggle the
left keyboard LED from green to off. This indicates that the CPU and motherboard is responding to
commands even if you see nothing on the displays. If nothing appears on the display(s) in order to further
debug the problem the 8230 must be put into its service position as documented in chapter 4 (8230XRA1)
or chapter 5 (8230XRA2/3).
6) With the 8230 in its service position refer to Figure 2-2 and find the System Status LED and Post Code
LEDs. Check for proper seating of the PCI Express graphics boards (the 8230XRA3 requires a 2
nd
PCI-E
graphics board for the left screen). Make sure the Poron is attached to the inside of the inner-chassis lid
as shown in Fig 5-33. Assuming the PCI-E boards are seated observe the LEDs in Figure 2-2. With the
motherboard in standby (after proper shutdown with AC applied) the System Status LED should be
yellow. Also both the yellow and green POST Code LEDs should be on.
7) Now depress the soft power button to turn on your 8230. The System Status LED should turn green. The
POST LEDs should sequence as follows: Yellow ON Green OFF during memory checks; Yellow OFF
Green ON during system shadowing checks; Yellow ON Green ON during final CPU checks; then Both
OFF just prior to the keyboard LED’s flashing.
