Ethernet Interface
6.1 Broadcom BCM56802 Switch
The ATCA-9305 supports multiple Ethernet interfaces. This chapter describes the Broadcom
BCM56802 switch, PHYS BCM5482 and BCM5461S, Ethernet address, LEDs and connectors.
The BCM56802 is a 16-port, 10-GbE multi-layer switch based on the StrataXGS
®
architecture.
The switch operates at 66 MHz with a 32-bit PCI bus for processor communication. SERDES
functionality includes 10-Gbps XAUI and 1-Gbps SGMII PHY interfaces.
One 10/100/1000BASE-T Ethernet (SGMII) port is routed to a front panel RJ45 connector (see
Figure 6-1 ), one is routed to the MPC8548 management processor TSEC2 port, and two are
routed to the base channel backplane (see Figure 8-2 ). Two 10 GbE XAUI ports connect to the
back panel via the fabric channel (see Figure 8-2 ).
Two XAUI ports process packets to and from each CN5860 processor. Six 10 GbE XAUI ports
route to the optional rear transition module (RTM). See
Table 8-3 and Table 8-4 for pin
assignments.
6.2 Ethernet Switching
The base interface Ethernet ports are provided by the Broadcom BCM56802 16-port, 10
gigabit (GbE) switch. The SerDes functionality includes 10-Gbps XAUI and 1-Gbps SGMII PHY
interfaces. The integrated SerDes complies with the CX-4 standard and PICMG 3.1 standard.
The Fabric interface is compliant with PICMG 3.1 Revision 1.0, specifically link option 9 (one
10GBASE-BX4). Switch connectivity consists of the following devices:
 Two 10GbE ports to CN5860 processor complex 1
 Two 10GbE ports to CN5860 processor complex 2
 One GbE port to the front panel (RJ45 connector)
 One GbE port to the MPC8548 management processor complex, then out the front panel
(RJ45 connector)
Proprietary information on the Broadcom switch is not available in this user’s manual. Refer
