Chapter Five Problem Solving
System Cooling Fans Do Not
Rotate Properly
If the system cooling fans are not operating properly, system components could be
damaged. Check the following:
q Is AC power available at the wall outlet?
q Is the system power cord properly connected to the system and the wall
outlet?
q Did you press the power button?
q Is the power on LED illuminated?
q Have any of the fan motors stopped (use the server management
subsystem to check the fan status)?
q Are the fan power connectors properly connected to the server board?
q Is the cable from the front panel board connected to the server board?
q Are the power supply cables properly connected to the server board?
q Are there any shorted wires caused by pinched cables or power connector
plugs forced into power connector sockets the wrong way?
If the switches and connections are correct and AC power is available at the wall
outlet, contact your Micron technical support representative for help.
Floppy Disk Drive Activity LED
Does Not Illuminate
Check the following:
q Are the Floppy Disk drive power and signal cables properly installed?
q Are all relevant switches and jumpers on the Floppy Disk drive set
correctly?
q Is the Floppy Disk drive properly configured?
q Is the Floppy Disk drive activity LED always on? If so, the signal cable
may be plugged in incorrectly.
If you are using the onboard diskette controller, use the SSU to make sure that
“Onboard Floppy” is set to “Enabled.” If you are using an add-in diskette controller,
make sure that “Onboard Floppy” is set to “Disabled.” Refer to run the SSU.
If the problem persists, there may be a problem with the Floppy Disk drive, server
board or drive signal cable. Contact your Micron technical support representative
for help.
