Powering-On Sequence of Multi-Tier Configuration
In a multi‐tier configuration, the order of powering ON is critical to
proper function.
When powering ON existing stable configurations (that is, if you are
NOT replacing or adding Paragon switches and NOT swapping their
order) or when you are Power Cycling a cascaded configuration, we
recommend that you power on the Paragon switches in the following
sequence:
1. Power ON the third tier (if a third tier exists).
2. Power ON the second tier.
3. Power ON the Paragon II base tier (first tier).
