Power-on Self test (POST)
The Switch performs its Power-On Self Test (POST) when the power is
switched on. During the POST, the switch CPU will:
Perform a series of diagnostic procedures to make sure the basic system is
functioning properly.
A command line prompts when you press the Esc key on a terminal
connected to the switch serial port during the POST process. Then you can
execute the following options:
DOWNLOAD RUNTIME SOFTWARE FROM SERIAL PORT0
This will download the runtime system image to the switch via the serial port.
Before selecting this option, make sure:
- A host system is running a terminal emulation program that supports the
Kermit file transfer protocol.
- The host system’s hard drive has the required binary file that will be
downloaded to the switch.
CONFIGURE THE SYSTEM
This option lets you modify any configurable parameter in the switch’s flash
ROM before the switch system boots.
RUN MANUFACTURING DIAGNOSTICS
This option is to download the manufacturer’s diagnostics. Refer to Download
Runtime Software for download requirements.
When the file transfer is completed, the target system jumps to the entry point
of the diagnostic program and starts executing the diagnostic code. The Main
Menu of the diagnostic program appears where you can initiate tests or
obtain system information. Note that user intervention is not required when a
test runs, unless an error occurs. If an error occurs during testing, you are
given the choice of continuing the diagnostics or skip the error.
