Management Module

Yellow Status LED for the Chassis on the Management Module is Lit
Issue 1.
1. Check the MLNX-OS management for confirmation and possible explanation of the
alert.
2. 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.
3. Make sure the S.Fans and L.Fans LEDs are green.
4. Make sure that the spine and the leafs both have the same version of FW.
5. Reburn the FW and remove and reinstall the management module.
6. If you are running the chassis with only one management module, remove and rein-
stall the management module. Make sure the mating connectors of the unit are free of
any dirt and/or obstacles. See Section 1.10.5 on page 54.
7. If you are running the chassis with only one management module, replace the man-
agement module.
Yellow LED for the Leaf Fan on the Management Module is Lit
Issue 2.
1. Check the MLNX-OS management for confirmation and possible explanation of the
alert.
2. 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).
3. 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.
4. Determine which fan module is problematic by checking the status LED on each fan
module.
5. Remove and reinstall the problematic fan unit. Make sure the mating connector of the
new unit is free of any dirt and/or obstacles. See Section 1.10.4 on page 51.
6. Replace the Leaf fan module.

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.
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.
Replace defective leaf fan modules as soon as they are identified.
