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 (i.e., if you are NOT replacing or adding
matrix switches and NOT swapping their order) or when you are Power Cycling a cascaded
configuration, we recommend that you power on the matrix 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).
Note that this order is reversed when upgrading a cascaded configuration.
1. Power ON the Paragon II base tier.
2. Power ON the second tier.
3. Power ON the third tier (if a third tier exists).
For configurations where matrix switches are added, replaced, or swapped (in order), we
recommend: powering ON starting from the third tier, then moving to the second tier, and then
the base tier, and in addition, performing a partial reset of the database.
User Stations can be powered ON and OFF at any time as needed.
There is a five-second ON/OFF down time in the matrix switch or Paragon II power cycle.
