Emerson ATCA-9305 Manuel D’Utilisation

ATCA-9305 User’s Manual

The ATCA-9305 supports multiple Ethernet interfaces. This chapter describes the Broadcom 
BCM56802 switch, PHYS BCM5482 and BCM5461S, Ethernet address, LEDs and connec-
tors.

The BCM56802 is a 16-port, 10-GbE multi-layer switch based on the StrataXGS® architec-
ture. 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 

), one is routed to the MPC8548 management processor TSEC2 port, and two 

are routed to the base channel backplane (see 

). Two 10 GbE XAUI ports connect to 

the back panel via the fabric channel (see 

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 

 and 

 for pin assign-

ments.

Note:

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)

• Two 10 GbE ports to the fabric interface

• Two 1 GbE ports to the base interface

• Two or six 10 GbE ports to the Zone 3 connector (optional RTM)
