•
If an external port on a SAN switch is disabled, the corresponding LED continues
to flash synchronously until the port is enabled through the chassis management
module, QuickTools, or the switch CLI.
For additional information about the chassis management module and enabling
ports through the chassis management module, see the following documents at

LED states and colors
After you install the switch in the IBM Flex System chassis, the switch LEDs become
active. There are four possible LED states: off, lit, flickering, and flashing. The lit
(steady) LEDs and flashing LEDs can be green, amber, or blue. A flickering LED can
only be green.
The LEDs might display any of these states and colors during startup, POST, or
other diagnostic tests. This behavior is typical and does not indicate a problem,
unless the LEDs indicate a problem after all the startup (boot) processes and
diagnostic tests have been completed.
•
Any errors that are detected during POST are written to the system log. This log
is accessible through the
show logging logfile
command in the switch CLI. For
information about this command, see the applicable command-line interface
guide at

Note:
You can also use the chassis management module to make sure that the
switch is operating correctly. For more information, see the documentation for the
IBM Flex System chassis.
