Inserting the Leaf Fan Module
1. Make sure the fan module is oriented correctly top side up. Confirm that the location
of the connector in the chassis will line up with the connector in the fan module.
2. Slowly slide in the new leaf fan module.
3. Push the fan module until the latch engages.
4. Make sure that the green leaf LED on the module comes on (indicating that fan is
running).

Handle
When hot-swapping any of the units, it is necessary to wait 1 minute after removing
the defective part before inserting the new part. This is necessary so that the manage-
ment module will start a new cycle checking through the leafs and spines for the FW
versions.
If the fan module stops before it goes in all of the way it is inserted incorrectly or it
may be for the other side of the chassis!
