SFP28 Module Connectors
[Figure 2-1, callouts 14, 15]
The ZCU111 board hosts four SFP28 connectors J27, J32, J37, and J42. The connectors are
housed within a single quad SFP28 cage assembly. The ganged SFP28 cage supports up to
four SFP/SFP+/SFP28 modules. Figure 3-23 shows the SFP28 module connector circuitry
typical of the four implementations.
Note:
The SFPx_TX_DISABLE default 2-pin jumper is On, which means the SFPx_TX_DISABLE net is
pulled Low, enabling the TX output of the SFP module.
