AM4901 Introduction
1. Introduction
1.1 MicroTCA™ System Overview
The MicroTCA™ Carrier Hub (MCH) described in this manual is based on the Micro
Telecommunications Computing Architecture (MicroTCA™ or µTCA™) defined by the
PCI Industrial Computer Manufacturers Group (PICMG®). The main advantages of
MicroTCA™ include high throughput, multi-protocol support, hot swappability, high scalability,
and integrated system management. For further information regarding the MicroTCA™
standard and its use, please consult the complete Micro Telecommunications Computing
Architecture Base Specification.
The Kontron MCH cards can be integrated into MicroTCA™ backplanes providing them with superior processing power and maximum design options. To learn more about the outstanding
features and advantages of Kontron MicroTCA™ systems, please contact Kontron or visit the
Kontron web site.
1.2 Board Overview
1.2.1 Board Introduction
The AM4901 is a MicroTCA™ Carrier Hub (MCH) implemented in the form factor of a Single,
Full-size Advanced Mezzanine Card (AMC) Module with a single tongue. It combines the
control and management infrastructure and the interconnect fabric resources needed to support up to twelve AMC modules, up to two cooling units and up to four power modules in a
MicroTCA™ system. The MCH’s design is based on the NXP® LPC2368 microcontroller and
the Broadcom BCM5396 Gigabit Ethernet switch.
The NXP® LPC2368 microcontroller includes a 16-bit/32-bit, 70 MHz, ARM7 CPU with integrated 512 kB Flash, 58 kB SRAM, I²C busses for IPMB usage, and an Ethernet interface. On
the AM4901, this microcontroller serves as the MicroTCA™ Carrier Management Controller
(MCMC) with electronic keying (E-Keying) support.
The Broadcom BCM5396 Gigabit Ethernet switch uses 14 SerDes/SGMII ports and combines
all functions of a high-speed base fabric including packet buffer, Media Access Controllers, address management and a non-blocking switch controller.
The AM4901 itself is hot swappable and uses E-Keying to provide hot swap capability for the
FRUs installed in a MicroTCA™ system, such as AMCs, cooling units and power modules, thus
enabling them to be replaced, monitored and controlled without having to shut down the MicroTCA™ system. Furthermore, it is able to monitor and control several onboard temperature
conditions of the FRUs, their board voltages and their power supply status, manage hot swap
operations, reboot them, etc.
P R E L I M I N A R Y
The AM4901 supports one standard RS-232 serial port, one Gigabit Ethernet uplink port for
fabric interconnection and one Ethernet port for carrier management as well as a variety of
high-speed interconnect topologies to the MicroTCA™ system, such as 12 SerDes connections in the Gigabit Ethernet Fabric [A], one additional SerDes connection for the MCH update
channel, 12 IPMB-L interfaces, two IPMB-0 interfaces, one Inter-MCH IPMB-L interface and
one cross-over channel interface.
ID 1022-5813, Rev. 1.0 Page 1 - 3

FEATURES SPECIFICATIONS
Module Management
LEDs
• LED1 (red): Out-of-Service LED
• LED2 (red/green/amber): Health LED
• HS LED (blue): The hot swap indicator provides basic feed-
back about the hot swap state of the module.
The HS LED states are off, short blink, long
blink, and on.
LEDs
Carrier Management
LEDs
• CMLED13 (green): Link signal from MCH update channel or the
MCMC
• CMLED12..1 (green): Link signal from the AMC SerDEs ports or
the MCMC
• CMLED0 (green): Indicates the input source for the
CMLED13..1 (Fabric [A] or MCMC)
MCMC • IPMI integrated in the NXP® LPC2368 microcontroller
• The MCMC receives the relevant IPMI events from the AMC modules
and carries out IPMI commands such as monitoring several onboard
temperature conditions, board voltages and the power supply status,
and managing hot swap operations
• The MCMC is accessible via a local IPMB (IPMB-L) bus, the serial port
IPMI
Hot Swap Full hot swap capability via E-Keying:
or the Ethernet port
• Hot swap capability of the AM4901 MCH
• Hot swap capability for the installed AMC modules
• Hot swap capability for the installed power modules and cooling units
Power Consumption See Chapter 4.2, “Power Considerations” for details.
