Ethernet Interface
The CPC5565 provides eight 10/100/1000Base-T Ethernet channels through the onboard
Broadcom BCM5389 8GbE Port Switch. Ethernet channels can be configured through the
BIOS setup utility, providing basic connectivity and functionality on power up and reset. See the
topic
“BIOS Configuration Overview” on page 40 for more information about the BIOS setup
utility.
The eight on-board Ethernet channels are as follows:
• Front panel RJ-45 connectors J8 and J9 (Front Panel A and Front Panel B BIOS setup options).
These connectors each have two LEDs to indicate the status of that channel.
• Two channels to midplane connector J3 (2.16 A and 2.16 B BIOS setup options)
• Two channels to optional on-board PMC site J11-J14 (PMC A and PMC B BIOS setup options). This
site provides an interface for a dual channel gigabit Ethernet PMC mezzanine card. The site
conforms to Option 7 of the PTMC Specification. The PMC card must have transformers on it to
provide isolation from the CPC5565. See the topic
“PTMC Interface (Build Option)” on page 28 for
more information about the site.
• Two channels to the host CPU via the 82571 dual NIC (ENET A and ENET B BIOS setup options).
The topic “Ethernet,” on page 115 , contains links to the product brief for the Broadcom
BCM5389 Ethernet controllers used on board the CPC5565. Connector locations and pinouts
are documented in
Chapter 5, “Connectors,” on page 85 .
