SFP28 (SFP1/SFP2/SFP3/SFP4) Connectors
Four small form-factor pluggable (SFP28) optical transceiver connectors (SFP1/
SFP2/SFP3/SFP4) are located on the add-on card. These SFP28 ports provide
Ethernet up to 25GbE network connections. See the layout below for the locations.
SFP28 (SFP1/SFP2/SFP3/SFP4) Link/Activity LED Indicators
Four SFP28 Activity/Link LED indicators are located at LED1, LED2, LED3, and
LED4 on the add-on card. LED1 is used for the SFP28 Port1 connector, LED2 for
SFP28 Port2 connector, LED3 for SFP28 Port3 connector, and LED4 for SFP28
Port4 connector. The SIOM LED1-LED4 are all dual bi-level LEDs: the top ones
are link indicators and the bottom ones are activity indicators. See the tables below
and image on the next page for the LEDs' states and functions.
