4.1 Planning for Updating Existing MDA or HDA Installations

First, see the entire discussion (above) about planning for new installations, then see additional
suggestions below.
When planning to install Leviton HDF3168 MDA Frame as an upgrade, the planner needs
to evaluate the cables, connectors, polarity method and hardware in the existing installation
(patch panels and cable management). HDX High Density cassettes and adapter plates can be
interchanged or replaced to provide migration from 10G to 40G or 100G.
The following are maximum recommended capacities for each HDF Frame by connector type:
40G and 100G systems are only recommended to use 18 Deck Units due to high trunk counts
and associated cable management limitations.

NOTE: When migrating, close analysis and attention must be made to match the existing polarity
method and breakout types. Mixing polarity methods will cause collision and connectivity issues
when mating cassettes and performing patching.
