Check the MLNX-OS management for confirmation and possible explanation
of the alert.
Reset the master management module by pushing the rest button. If you have
two management modules installed this will convert the master management
module to the slave and convert the slave to the master.
If there is only one management module in the chassis all of the leafs and ports are reset
by bringing them down and powering them up when the management module is
removed.
Make sure the S.Fans and L.Fans LEDs are green.
Make sure that the spine and the leafs both have the same version of FW.
Reburn the FW and remove and reinstall the management module.
If you are running the chassis with only one management module, remove and
reinstall the management module. Make sure the mating connectors of the
unit are free of any dirt and/or obstacles. See Section 5.5 on page 73.
If you are running the chassis with only one management module, replace the
management module.
Check the MLNX-OS management for confirmation and possible explanation
of the alert.
Make sure that there is nothing blocking the front or rear of the chassis and
that the fan modules and ventilation holes are not blocked (especially dust
over the holes).
If you find dust blocking the holes it is recommended to clean the fan unit and
remove the dust from the front and rear panels of the switch using a vacuum
cleaner.
Determine which fan module is problematic by checking the status LED on
each fan module.
Remove and reinstall the problematic fan unit. Make sure the mating connec-
tor of the new unit is free of any dirt and/or obstacles. See Section 5.4 on page
70.
Replace the Leaf fan module.
There are two non-interchangeable types of leaf fan modules. If the new leaf fan does
not go into the chassis confirm that it is the correct fan module.
