Troubleshooting Checklists; Initial System Start-Up - NEC LS2400 User Manual

Troubleshooting Checklists

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.
Initial System Startup
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:
T
Is the system power cord properly connected to the
system and plugged into a NEMA 5-15R outlet (100-120
V ac) or a NEMA 6-15R outlet (200-240 V ac)?
T
Is AC power available at the wall outlet?
T
Is the power on/off push-button switch on the front
panel in the ON position (power on LED should be lit)?
T
Are all cables correctly connected and secured?
T
Are all the PCI/ISA option boards fully seated in their
connector slots on the system board?
T
Are all jumper settings on the system board correct? For
jumper information, see the "Configuring Your System"
chapter?
T
Are all jumpers and switch settings on option boards and
peripheral devices correct? To check these settings, see
the respective appendices. If applicable, ensure that
there are no conflicts; for example, two option boards
sharing the same interrupt.
T
Are the processors fully seated in their slots on the
system board? Refer to the "Upgrades and Options"
chapter for installation instructions?
