®
AMC.0 Revision 2.0 Advanced Mezzanine Card Base Specification with the
exception of a couple non-conformances. See the KAT4000 Errata for details. Each AMC site
is individually configurable. Chapter 8 provides more information.
System Management: The KAT4000 supports an Intelligent Platform Management Interface (IPMI) based on a
Renesas microcontroller with a UART interface for processor to IPMC communication (fixed
rate at 115,200 baud) and dual redundant IPMB-A/B interfaces. The IPMC allows for fea-
tures such as remote shutdown, remote reset, payload voltage monitoring, temperature
monitoring, and access to Field Replaceable Unit (FRU) data. Chapter 9 provides more
information.
Synchronization Clock: The synchronization clock interface consists of MT9045 or MT9046 T1/E1 system synchro-
nizers. Chapter10 provides more information.
RTC: The Real-Time Clock (RTC) is an ST

Caution: There are no serviceable parts in this product. Return all damaged boards to Emerson for
repair (see page 2-18).
KAT4000 Options
No-CPU Configuration: A no-CPU KAT4000 board configuration is available. This configuration includes 256 Kb of
SRAM memory used by the internal 8051 microcontroller on the VSC7376 Ethernet core
switch for run time code storage. This configuration omits SDRAM and NOR and NAND
flash. Appendix A provides more information.
Ethernet Core Switch: The Ethernet core switch provides the interconnect between the fat pipe switch module,
the Ethernet ports on the AMC sites, two channels on the ATCA backplane Base fabric, the
processor, and the Update Channel (optional). A Vitesse VSC7376 GbE switch implements
this function. “Ethernet Core Switch (optional)” on page 4-2 provides more information.
PCI Express Switch: The PCIe switch provides the interconnect between the AMC sites, the processor, and the
fat pipe switch module. A PLX Technology PEX 8524 PCIe switch implements this function.
“PCI Express Switch (optional)” on page 4-7 provides more information.
Note: Of the Ethernet core switch and the PCI Express switch, at least one of the two switches must be used on the
board. The board can also use both switches.
