System Troubleshooting
H.1 Unit does not power up
Consideration should be given to the connection of the equipment to the supply circuit and the eect that overloading of circuits
could have on overcurrent protection and supply wiring.
Questions to ask beforehand (to help nd root cause of issue):
• Was the unit working beforehand? If so, for how long?
• Did anything happen that may have caused this (lightning strike, power failure)?
• Is this unit on a UPS? If so, is it connected on the power-protected side and not the surge side?

• Visually inspect whether the LEDs are on and the power supply and CPU fans are operating.
• Switch the power cord to another outlet.
• Switch to another power cord.
• Open the cover to check voltages with a voltmeter on the power supply. These should be 12v and 5v.
• Inspect the main board for bulging capacitors.
• Check the processor heat sink and make sure it is properly installed.
• Check the diagnostic lights for hardware reference. Boot the system with the Recovery CD in the drive. Go into the Tools area

connector.
