Name and Function
This pin is a strapping pin latched at the rising edge of LAN_PWR_GOOD,
Internal Power On Reset, PE_RST_N, or in-band PCIe reset. If this pin is
not connected or driven high during initialization, LAN 1 is enabled. If this
pin is driven low during initialization, LAN 1 port is disabled.
This pin controls the ability to put external PHY 0 in power down mode
according to the 82598’s internal power state.
This pin controls the ability to put external PHY 1 in power down mode
according to the 82598’s internal power state.
Bypass indication as to whether or not to use Internal Power On Reset or
the LAN_PWR_GOOD pin. When high, the 82598 disables the Internal
Power On Reset circuit and uses the LAN_PWR_GOOD pin as the power on
reset indication.
Main Power OK. Indicates that platform main power is up. Must be
connected externally.
