Nortel Networks 24T manual LED Indications During the Software Download Process

Using the Console Interface

During the download process, the BayStack 410-24T switch is not operational. You can monitor the progress of the download process by observing the LED indications.

Table 3-38 describes the LED indications during the software download process.

Note: The LED indications described in Table 3-38 apply to a 24-port switch model. Although a 12-port switch provides similar LED indications, the LED indication sequence is associated within the 12-port range.

		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.

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

Link 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.

Link 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’s 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.
