1.10.5.1 Inserting a Management Module
To insert a management board:
1. Check for foreign objects in or mechanical damage to the chassis management slots.

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.
