3.1.2 Base Switch
The base switch is a Broadcom BCM56500 (full featured version) or BCM56300 (lite featured
version) 24 port GbE multilayer switch that can operate in 10/100/1000 Mbps. It integrates ad-
vanced Layer 3 switching features for IPv4 and IPv6 routing. The BCM56500 also includes en-
hanced QoS support and jumbo packet line rate switching.
The PPC controls the switch over a 32bit/66MHz PCI Interface.
Base Interface (Zone 2)
The board supports 15+2 ATCA backplane channels. The board can operate in a dual star and
full mesh configuration. The switch is connected to the backplane via four 10/100/1000BASE-
T quad PHYs and eight 10/100/1000BASE-T dual magnetics. The pin assignment for the Zone
2 connectors is compliant to the PICMG 3.0 standard. GbE channels 0/20 and 0/24 of the
switch are the 100BASE-TX ShMC base channels (ShMC cross-connects).
