NEC 5800/180Ra-7 Manuale Utente

The following subsections provide troubleshooting checklists for problems that occur at
initial system startup, when you run new application software, and after the system
hardware and software have been running correctly.

Incorrect installation or configuration usually causes problems that occur at initial
system startup. Hardware failure is a less frequent cause. If you have problems during
initial system startup, check the following:

!

 

Are the system power cords properly connected to the system and plugged into a
NEMA 5-15R outlet (100-120 Vac), a NEMA 6-15R outlet (200-240 Vac), or an
UPS that meets the power specifications of the system?

!

 

Is AC power available at the wall outlet?

!

 

Are two or more power supplies installed properly after installation of the optional
8-way upgrade kit?

!

 

Is the front bezel of the server mounted properly? A sensor to detect if the cover is
open monitors the front bezel. If the bezel is not mounted properly power is not
supplied to the server system.

!

 

Is the power on/off push-button switch on the front panel in the ON position (power
on LED should be lit)?

!

 

Are all cables correctly connected and secured?

!

 

Are all the PCI option boards fully seated in their connector slots on the system I/O
board?

!

 

Are all jumpers and switch settings on option boards and peripheral devices correct?
If applicable, ensure that there are no conflicts; for example, two option boards
sharing the same interrupt.

!

 

Are the processors fully seated in their slots on the baseboard or CPU boards? Refer
to the Processors subsection of Upgrading Your System chapter 4 for installation
instructions?

!

 

Are all DIMMs fully seated and installed correctly? Refer to the DIMMs subsection
of Upgrading Your System chapter 4 for installation instructions.

!

 

Are all option boards and disk drives installed correctly? Refer to the Options
Boards and Hard Disk Drives subsections of Upgrading Your System chapter 4.

!

 

Is the system hard disk drive properly formatted or defined?

!

 

Is the operating system properly loaded? Refer to the operating system
documentation.

!

 

Are all drivers properly installed? For information about installing drivers, refer to
your Network Operating System Configuration Guide.
