54 I2C_SMCLK Micro coax PCIe compliant
SMBus interface to
the network adapter.
The Network adapter
silicon may be
accessed through
this SMBus interface
after the Power-On
sequence of the
network adapter is
completed. The
motherboard side
serves as the bus
master on the SMBus
interface. (Please
note on AUX board
implementation, an
I2C EEPROM at
address 0x50 is also
present on this
interface, to allow
the server
management entity
to read the identity
of the auxiliary card.
For a direct
motherboard
interface to the
Cabline CA-II Plus
cables, mounting
such FRU EEPROM on
the motherboard
should be considered
– for motherboard
management
purposes of the
Cabline CA-II Plus
interface to the
network adapter).
