8.9.7 Block Diagram
Figure 8-22 shows a block diagram of the MXP_MR_2.5G card. The card has eight SFP client interfaces.
Ports 1 and 2 can be used for GE, FC, FICON, or ESCON. Ports 3 through 8 are used for ESCON client
interfaces. There are two SERDES blocks dedicated to the high-speed interfaces (GE, FC, FICON, and
ESCON) and two SERDES blocks for the ESCON interfaces. A FPGA is provided to support different
configurations for different modes of operation. This FPGA has a Universal Test and Operations
