Power-On Self-Test (Netfinity 7000 - 8651)
Power-On Self-Test (POST)
Each time you power-on the system, it performs a series of
tests that check the operation of the system and some
options. This series of tests is called the power-on
self-test, or POST POST does the following.
- Checks some basic system-board operations
- Checks the memory operation
- Starts the video operation
- Detects and initializes ISA devices
- Detects and configures EISA devices
- Detects and configures PCI devices
- Verifies that the diskette drive, hard disk drive, and
other installed devices are working
Check the indicator lights on the front of the server and the
back ot the power supplies. Verify that all of the amber
lights are off. If an amber lights are on, see 'Status Indicators'.
Verify that both green LEDs on the
back of the power supplies are on. Verify that all server
devices are operating properly. If a device is not operating
properly, ensure that it is not defective and is installed
correctly. Replace defective devices and reinstall any
device that is not installed correctly.
If POST finishes without detecting any problems, a single
beep sounds and the first screen of the operating system
or application program appears. If no operating system is
installed, Ihe system prompts you to insert bootable media.
Refer te the information that came with the ServerGuide
package for instructions on installing an operating system.
If POST detects a problem, an error message appears on
the screen. A single problem can cause several error
messages to appear. When you correct the cause of the
first error message, the other error messages probably will
not appear on the screen the next time you power-on the
system.
