Technical Product Specification
Intel® Remote Management Module IntelP®P RMM Board Architecture
3.1 Media Independent Interface (MII)
A Media Independent Interface (MII) connects to the MAC of the dedicated Ethernet NIC of the
Intel
®
RMM to the Ethernet PHY located on the Intel
®
RMM NIC. The MII interface from the
Intel
®
ASMI connector is wired to the MII pins of the Davicom DM9000E Fast Ethernet Controller
(NIC) chip* on the Intel
®
RMM.
The Davicom NIC* is connected on board to the local bus of the Intel XScale® processor
PXA255. The Davicom NIC* provides the dedicated, Out Of Band (OOB) 10/100 Mb/S Ethernet
capability to the Intel
®
RMM.
3.2 B 2.0 (high-speed) Interface
A USB 2.0 (high-speed) interface supports the following:
ual keyboard
ual mouse
l
®
RMM - Virtual Media
al utilities
The USB interface from the Intel
®
ASMI connector is wired to the USB pins of the Phillips 1583
USB 2.0 High Speed interface chip*. The Phillips USB chip* is connected on board to the local
bus of the Intel XScale® processor PXA255
3.3 2 Serial Port Connection
O erial port connection of the Intel
®
ASMI is connected to the Serial port connection
I cale® processor PXA255 on the Intel
®
RMM. On the baseboard, the Intel
®
ASMI
c erial port pins are connected to the system universal asynchronous receiver
ART) within the SIO chip. This connection is to enable serial text console

c e Intel XScale® processor PXA255 on the Intel
®
RMM. This IPMB interface
c Intel
®
RMM to the BMC.
n M provides IPMI satellite controller functionality to the BMC. The IPMB of the
RMM provides bi-directional communication at 100 KHz.
Pins
s on the Intel XScale
