Interpreting switch fabric module LEDs
Refer to the following illustrations and table to interpret the LED patterns for the switch fabric module (SFM). The LED patterns may
temporarily change during device diagnostic tests.
Since the SFM is located behind the fan modules, LEDs are provided on the fan and management modules to check SFM status. For
the location of the SFM LEDs on the management module, refer to
Interpreting management module LEDs on page 75. For the
location of the SFM LEDs on the fan module, refer to Interpreting fan module LEDs on page 83.
There is also a label on the bottom center of the chassis that shows the SFM locations behind the fan modules.
If the fan module is removed, you can check the LEDs on the SFM, as shown in the following figure.
