[1.3.119] LAN on Motherboard
[1.3.120] The S210-MBT2W Server will use the Intel® I350
code named Powerville Quad 10/100/1000 integrated MAC and
PHY controller. The Powerville LOM requires a PCIe x4 Gen2
upstream interface. When connected to a CPU Gen3 interface,
the Gen3 will downshift to Gen2.
[1.3.121] The Powerville LAN controller will be on standby
power so that Wake on LAN and manageability functions can
be supported.
[1.3.122] It is expected that Powerville support the normal
LINK/Activity speed LEDS as well as the Proset ID function,
and that should connect the Powerville LAN port LED signals to
the corresponding RJ45 connector LEDs. These LEDs should
be powered from a standby voltage rail.
[1.3.123] Powerville will be used in conjunction with the
ASPEED AST2300 BMC for out of band Management traffic.
The BMC will communicate with Powerville over a NC-SI inter-
face (RMII physical). Powerville will be on standby power so
that the IBMC can send management traffic over the NC-SI
interface to the network during sleep states, S3, S4 and S5.
[1.3.124] Powerville Thermal Sensor
[1.3.125] Powerville will have a integrated digital thermal sen-
sor accessible through CSR and manageability registers. The
thermal sensor can be programmed to trigger digital pins and
thermal throttling with hysteresis. There will also be thermal
diode. The thermal diode is primarily designed for lab usage.
The development team should use the Powerville thermal sen-
sor in the FSC (fan speed algorithm).
[1.3.126] NIC Status LED
[1.3.127] The S210-MBT2W design needs to ensure that the
following scheme for the NIC Speed is incorporated into the
EEPROM.
