Solving Simple Problems
Some system problems are simple ones and easy to solve. Check the corrective actions to the general problems in the following table. If you still have a problem, record the conditions of the problem and contact your system administrator or NEC support personnel.
!WARNING
Some locations within the server have high voltage and therefore are very dangerous. To avoid risk of electric shock, turn off all server power and disconnect power cables.
The main power of your server is turned off by turning off the power distribution board or removing the power cable.
Before touching the parts in the server, wait for at least 10 to 15 seconds until residual voltage is discharged.
!CAUTION
An electrostatic discharge (ESD) can damage disk drives, option boards, and other components. You can provide some ESD protection by wearing an antistatic wrist strap attached to chassis ground when handling system components.
Electronic devices can be easily damaged by static electricity. To prevent damage, keep them in their protective packaging when they are not installed in your system.
