Section 4
Common Switch Region
The KAT4000 supports multiple interfaces. This chapter describes the Ethernet core switch,
switch configuration, Ethernet address and PCI Express switch. The board area network
(BAN) refers to the routing of the Ethernet ports using the Vitesse VSC7376 Gigabit Ether-
net (GbE) core switch or the PCIe ports using the PEX 8524 PCI Express switch. The Ethernet
core switch provides the interconnect between the fat pipe switch module, the Ethernet
ports on the AMC sites, the processor, two channels on the ATCA backplane base fabric,
Zone 3, and the Update Channel (optional) (see
Fig. 4-1). The PCI Express switch provides
the interconnect between the AMC sites, the processor, and the fat pipe switch module.
Both switches are optional, however at least one of the two must be used on the board. The
board can also use both switches.
