Resetting The System; Troubleshooting Checklists; Initial System Startup - NEC HX4500 User Manual

This chapter helps you identify and solve problems that may occur during
system installation or while using your system. The first section of this chapter
tells you how to reset your system in the event of problems. The next few
sections provide troubleshooting checklists and procedural steps that help you
isolate specific system problems. The last sections include error message and
status LED user information.
The DC push-button on/off switch on the front panel does
not turn off the system AC power. Before doing the following
procedures, make sure that your system is powered off and
unplug the AC power cords from the back of the chassis.
Failure to disconnect power before opening your system can
result in personal injury and equipment damage.

Resetting the System

There are two ways to reset the system.
Reset button
Pushing the reset button clears the system memory, restarts the POST, and
reloads the operating system.
Power off/on
Turning the power off and then on with the push-button switch on the front
panel has the same effect as pushing the reset button, except that power is
halted to all peripherals.

Troubleshooting Checklists

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

Initial System Startup

Problems that occur at initial system startup are usually caused by incorrect
installation or configuration. Hardware failure is a less frequent cause. If you
have problems during initial system startup, check the following.
T
Are the system power cords properly connected to the system and
plugged into NEMA 5-15R outlets (100-120 Vac) or NEMA 6-15R
outlets (200-240 Vac)?
T
Is AC available at the wall outlets?
T
Is the power on/off push-button switch on the front panel in the ON
position (power on LED should be lit)?
