The current port count limit (up to and including version 5.2.3) on Eclipse is 240 ports per matrix. Here is what counts towards this limit:

• MVX
• MADI 
• IVC-32
• E-QUE direct
• Beltpack roles

Anything else, namely E-QUE cards in antenna, splitter or trunking modes and E-FIB cards, don't count against this limit. However, if any of those cards are followed by an MVX or E-QUE direct card, they do count. So the order in which the cards are configured is important. Here is an example:

Slots 1-7 MVX (port 1 to 112)

Slots 8-9 E-QUE Splitter (port 113 to 232)

Slot 10 MVX (port 233 to 248)

The example configuration above would not compile. Since the E-QUE Splitter cards are followed by an MVX, their individual port count (60) counts towards the total port limit. Reordering the cards however will fix this:

Slots 1-7 MVX (port 1 to 112)

Slot 10 MVX (port 113 to 128) 

Slots 14-15 E-QUE Splitter

This reordered example configuration would compile (not considering configured beltpack roles).
At ECS 5.2.4 you had the following limits:240 audio ports496 time-slots- Every audio port used up one time-slot as well. So a 64 port MADI card would use 64 audio ports and 64 time-slots. 
An E-FIB set to 192 trunks uses 0 audio ports (as long as there are no cards with audio parts in a slot with 
a higher number) and 192 time-slots.

FreeSpeak Role/virtual port count in ECS 5.2.4.I understood that the FSPK role takes up a virtual port count on the system.   Yes,  it’s the number of configured FS  Roles with draw from system capacity … not the absolute number of ports on a E-Que card.
Concert- dynamic allocation vs. Static assignment on the IVC-32.Customer has chosen 100 concert licenses to serve all of their audio and video post suites. Customer thinks that allocation to the IVC card was dynamic where I was sure you allocate a Concert panel to a virtual port on the IVC card within ECS. Can you clarify?Each IVC-32 has a fixed footprint of 32 ports … Each of these IVC-32 ports  is configured for a specific operator. 96 individual operators require 3 x IVC-32 cards LMC-64 port count:does the LMC-64 meters add to the port count or are they virtual?the LMC-64 meters add to the port count and take away from the 240 port limit , therefore they should be placed before EQUE and E-FIB cards in the matrix
