The fabric modules must be installed in specific slots as follows (installing fabric modules in other slots can
cause a module mismatch condition):
•
For three modules, they must be in slots FM 2, FM 4, and FM 6.
•
For four modules, they must be in slots FM 2, FM 3, FM 4, and FM 6.
•
For five modules, they can be in slots FM 1, FM 2, FM 3, FM 4, and FM 6. Alternatively, they can be
in slots FM2, FM3, FM4, FM5, and FM6.
•
For six modules, they will be in slots FM 1, FM 2, FM 3, FM 4, FM 5, and FM 6.
Fabric slots FM 2, FM 4, or FM 6 must be filled with functioning fabric modules or blank modules with
power connectors (N9K-C9508-FM-Z) in order to provide power to the fan trays covering those modules.
If fabric slots FM 1, FM 3, or FM 5 are not filled with a fabric module, you must make sure that they have
a blank module (N9K-C9508-FM-CV) installed to preserve the designed airflow.
Note
You can replace a fabric module while other fabric modules are operating by removing the fan tray in front
of the fabric module, removing the fabric module, installing the new fabric module, and replacing the fan tray
over the installed fabric module.
To maintain the designed airflow while you remove the fan tray, the fans in the other fan trays increase their
speed. During operations, we recommend that you remove only one fan tray at a time and reinstall that fan
tray within three minutes to avoid the possibility of having the switch overheat and shut down.
If you remove more than one fan tray at a time, the switch will shut down if you do not reinstall the extra
missing fan trays within two minutes (the shutdown can occur earlier if the switch over heats).
