Question:  What needs to be upgraded on an IVC-32 card on a Eclipse frame being upgraded from ECS 5.1 to ECS 5.2?
Answer:  The following procedure attached below describes how to upgrade an E-QUE card. However, the same procedure is also used for upgrading IVC-32 and LMC-64 cards. Use the following procedure for upgrading EQUE, IVC-32 or LMC-64 cards.  At ECS V5.2 the application code (firmware) for all 3 cards is the same:
710807Z     E-QUE FPGA code    ECS 5.2.2 (v14) was v13 in ECS 5.1.3
710809Z     E-QUE App code       ECS 5.2.2 (3.10.5) was 2.0.35 in ECS 5.1.3
710.810Z    E-QUE Boot code      ECS 5.2.2 (1.4)  last updated in ECS 5.0.3
The recommended upgrades for ECS 5.2 are the FPGA code and and the application code.  The boot prom code doesn't need to be upgraded. 
The user will need the MVX upgrade cable and access to the Tera Term terminal software program and the TFTP server application to upgrade the 710809Z application code. 
The user will need access to the Xilinx programmer and software to upgrade the 710807Z FPGA code. 
It is also advised to check the dip switch settings on the card, for the IVC-32 application the settings need to be:
1 - off 
2 - on
3 - off
4 - off
If the IVC-32 dip switch settings are all set to "off" the card's Ethernet port will only operate in half-duplex mode and could cause connection issues to V-Panels / Concert Panels. 
As noted above the complete upgrade instructions are attached below.
