connectors. The networking connectors allow for the use of modules, optical and
passive cable interconnect solutions.
There are two I/O LEDs, LED0 and LED1, per port to indicate speed and link
status.
FRU EEPROM capacity 4Kb
Allows BMC connectivity using MCTP over SMBus or MCTP over PCIe protocols.
Voltage supply pins that feed onboard regulators.
Controls the networking port LEDs.
