PHY Management Interfaces
The BCM84754 provides a single MDC/MDIO management port to access all four channels and
allows bits 0 and 1 of the PHY address for each channel to be individually programmed, with
bits 2 - 4 being common.Table 9 shows the address allocation and management port definition
for each channel.

40Gbps Fabric Ports
The RTM-ATCA-F140 provides a 40Gbps capable QSFP+ module site connected to the fabric
switch on the front blade.
4.6.1
Fabric Connectivity
One 40GbE port fom the front blade fabric switch connects to a BCM84740 quad XLAUI-to-SFI
PHY which then connects to a single QSFP+ connector using an SFI interface as shown in
. When the fabric switch is configured for XLAUI mode, the QSFP+
slot supports a single 40GbE logical connection. When the fabric switch is configured for 4x XFI
mode, the QSFP+ slot supports four 10GbE connections. This mode assumes the use of a fiber
breakout cable on the QSFP+ module (MPO to 4x LC cable). The RTM-ATCA-F140 includes
