Maintenance & Troubleshooting
Replacing the UCP
-
3901’s Fan
Re-apply power to the UCP
-
3901 and restore system operation to see if the fan alarm
becomes inactive.
The UCP
-
3901’s onboard circuitry monitors the fan motor’s rotational speed to detect that
the fan is rotating fast enough to provide sufficient cooling; it raises a fan alarm when the
fan’s rotational speed has gone below a factory-set threshold.
When the UCP
-
3901’s fan is not rotating fast enough (as detected by a fan alarm), is making
abnormal noises, or is not rotating at all, the fan is worn out and it must be replaced with a
new one.

Required Tools
The following field-supplied material is required:
• Compressed air to remove dust from the UCP
-
3901.
• Needle-nose pliers to separate push pins from the PCB.
• Curved tweezers to disconnect the fan’s power connector from the UCP
-
3901’s main
board.
• Anti-static bag or anti-static work surface to reduce the possibility of electrostatic
discharge damage to the UCP
-
3901’s electronics.
Cooling Fan Replacement Procedure
The cooling fan is located on the UCP
-
3901 PCB card.
