2-6 Sun Netra CP3240 Switch Installation Guide • September 2009
2.2 Switch Components
The following sections list and describe key components of the Sun Netra CP3240
switch.
2.2.1 Broadcom StrataXGS 3 BCM56503 Ethernet Switch
The Sun Netra CP3240 switch uses Broadcom StrataXGS 3 BCM56503 for Base
Ethernet switching/routing. This chip is an Ethernet switch with 24 1Gigabyte ports
and 3 10Gigabyte ports. It provides non-blocking, wire-speed switching and routing
on all ports under 100% load. The BCM56503 features many advanced features
presented to the user via the FASTPATH software. See the Section 4.10, “FASTPATH”
on page 4-18 for more information.
2.2.2 Broadcom StrataXGS 3 BCM56800 Ethernet Switch
The Sun Netra CP3240 switch uses Broadcom StrataXGS 3 BCM56800 for Fabric
Ethernet switching/routing. This chip is an Ethernet switch with 20 10Gigabyte
ports. It provides non-blocking, wire-speed switching and routing on all ports under
100% load. The BCM56800 features many advanced features presented to the user
via the FASTPATH software. See Section 4.10, “FASTPATH” on page 4-18 for more
information.
2.2.3 Broadcom BCM5464R and BCM5461S
10/100/1000Base-T Ethernet PHY
Quad and single ports respectively, the Broadcom PHYs provide the physical
interfacing for 10/100/1000Base-T. They are low-power devices and provide features
such as jumbo frames support, auto-MDIX, and cable testing.
