86

Power management support (D31:F0) including ACPI S3 state support (suspend to RAM)
and Management Engine Power Management support

High Precision Event Timers (HPET)

System TCO (total cost of ownership) Reduction circuits

SMBus Host controller (D31:F3) and SMLINK0,1 interface for communication with external
IPMC controller

General purpose I/O pins (D31:F0)
4.4.2 Intel i350 Quad GB Ethernet Controller
The i350 four 1Gb Ethernet MACs are used on ATCA-7480 to provide:

Dual AdvancedTCA Base Interface 10/100/1000Base-T

Two Faceplate 10/100/1000Base-T interfaces
4.4.3 Firmware Flashes
The Blade has two physically separate 16 MB flash devices hosting the BIOS firmware.

Primary (or Default BIOS) Flash (SPI 0)

Recovery BIOS Flash (SPI 1)
The flash is allocated for storing the binary code of the BIOS. The ATCA-7480 boots from the
primary flash SPI 0 under normal circumstances. If booting BIOS from primary flash SPI 0 fails,
a hardware mechanism automatically changes the flash device select logic to boot from the
recovery flash SPI 1. The image that the processor will boot from after next reset is determined
by the IPMC. It can be selected via dedicated IPMI OEM command.
4.5 ATCA Fabric IF Ethernet
The ATCA-7480 blade utilizes two Intel XL710 Dual 40GB Ethernet controllers to provide four
40GB Ethernet IFs to the ATCA zone 2. They operate at 40GBASE-KR4,10GBASE-KR,10GBASE-
KX4,1000Base-KX: Option1, 1-K,1-KR,9,9-K,9-KR. The redundant fabric I/F is fully operable in
40G, 10G, or 1G mode without the presence of an RTM.
