Troubleshooting Procedures
Use the following procedures to troubleshoot your system. If you have
followed all of the procedures below and still need assistance, refer to the
‘Technical Support Procedures’ and/or ‘Returning Merchandise for Service’
section(s) in this chapter.
Note: Always disconnect the power cord before adding, changing
or installing any hardware components.
Notes:
1) It might take longer than usual (up to 40 seconds) to boot up the system.
(The larger the memory size is, the longer it will take to boot the
system.)
2) Please wait at least 10 seconds between power off and power on for
proper VRMs discharge.
3) The i2DML-8G2/iG2 supports Limited ACPI functions (only the functions
of: “S0-Active”, and “S5-Complete power off” are supported).
4) The minimum power requirement is 500W and above. Also, two 4-pin
12V/15A power connectors are required for CPU Power Pods (VRMs).
5) There is no BIOS Recovery function available. Should a problem occur
after flashing BIOS, all six BIOS chips will have to be replaced
.
Before Power On
1. Make sure no short circuits exist between the motherboard and chassis.
2. Disconnect all ribbon/wire cables from the motherboard, including those
for the keyboard and mouse.
3. Remove all add-on cards.
4. Install one CPU (making sure it is fully seated) and connect the chassis
speaker and the power LED to the motherboard. (Check all jumper
settings as well.)
No Power
1. Make sure no short circuits exist between the motherboard and the chas-
sis. (*Disconnect the AC plug from the power supply for more than 2
minutes to reset short circuit protection.)
2. Verify that all jumpers are set to their default positions.
3. Check that the 115V/230V switch on the power supply is properly set.
4. Connect the AC plug to the power supply, and turn the power switch on
