Table 3-29. LED Indications During the Software Download Process

Phase Description LED Indications

1The switch downloads the new 100 Mb/s port status LEDs (ports 18 to 24 only): The

software image.	LEDs begin to turn on in succession beginning with port 24,
	which indicates the progress of the download process. When
	LEDs 18 to 24 are all on, the switch has received the new
	software image successfully.

2The switch erases the flash memory.

100 Mb/s port status LEDs (ports 1 to 12 only): The LEDs begin to turn on in succession beginning with port 1, which indicates that various sectors of the switch’s flash memory are being erased. When LEDs 1 to 12 are all on, the switch’s flash memory has been erased.

3The switch programs the new software image into the flash memory.

100 Mb/s port status LEDs (ports 1 to 8 only): The LEDs begin to turn on in succession beginning with port 1, which indicates that the new software image is being programmed into the switch’s flash memory. When LEDs 1 to 8 are all on, the new software image has been programmed successfully into the switch’s flash memory.

4The switch resets automatically. After the reset completes, the new software image initiates the switch self-test, which comprises various diagnostic routines and subtests.

The LEDs display various patterns to indicate that the subtests are in progress. The results of the self-test are displayed briefly in the Self-Test screen, after which the CI screens appear.
