NEC HX4500 manual Resetting the System, Troubleshooting Checklists, Initial System Startup

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.

!WARNING

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

urning 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.

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)?

TIs AC available at the wall outlets?

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