 Manageability Features
3.3.1 Low Pin Count (LPC) Interface
The chipset implements an LPC Interface as described in the LPC 1.1 Specification and
provides support for up to two Master/DMI devices. On the server board, the LPC interface is
utilized as an interconnect between the chipset and the Integrated Base Board Management
Controller (Integrated BMC) as well as providing support for the optional Trusted Platform
Module (TMP).
3.3.2 Universal Serial Bus (USB) Controller
The chipset has two Enhanced Host Controller Interface (EHCI) host controllers that support
USB high-speed signaling. High-speed USB 2.0 allows data transfers up to 480 Mb/s which is
40 times faster than full-speed USB. The server board utilizes nine USB 2.0 ports from the
chipset. All ports are high-speed, full- speed, and low-speed capable.
 Four external USB ports are provided in a stacked housing located on the rear I/O
section of the server board.
 Four USB ports are routed to two internal 10-pin connectors that can be cabled for front
panel support.
 One internal Type ‘A’ USB port.
