893-00992-D
Table 3-23 describes the LED indications displayed by the Model 350T during the
software download process. Other BayStack 350 Series models show similar
indications, but the indications correspond to the port numbers for the specific
model.
Table 3-23. LED indications during the software download process
Phase Description LED indications
1 The new software
image is being
downloaded to
the switch.
100 Mb/s port status LEDs (ports 11 to 16 only): The LEDs (green) begin to
turn on from right to left, beginning with port 16. The LED pattern indicates
the progress of the download process. When LEDs 11 to 16 are all on, this
indicates that the switch has received the new software image
successfully.
2 The switch’s flash
memory is being
erased.
10 Mb/s port status LEDs (ports 1 to 9 only): The LEDs (yellow) begin to
turn on from left to right, beginning with port 1. The LED pattern indicates
that various sectors of the switch’s flash memory are being erased. When
LEDs 1 to 9 are all on, this indicates that the switch’s flash memory has
been erased.
3 The new software
image is being
programmed into the
switch’s flash
memory.
100 Mb/s port status LEDs (ports 1 to 8 only): The LEDs (green) begin to
turn on from left to right, beginning with port 1. The LED pattern indicates
that the new software image is being programmed into the switch’s flash
memory. After LEDs 1 to 8 are all on, LEDs 9 to 16 turn on, indicating that
the new software image has been programmed successfully into the
switch’s flash memory.
4 The switch is reset
automatically.
The reset can take up to 20 seconds to complete. After the reset is
complete, 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, which is followed by the CI screens.
