ATCA-8310 Installation and Use (6806800M72E) 91
4.5.3 ATCA Fabric Interface
The redundant (dual) Fabric Interface of the ATCA-8310 is provided by the Switching Unit. Two
XAUI-Ports of the BCM56624 are directly connected to the Zone2, providing the ATCA Fabric
Interface on connector P23 rows #4,#3 (Fabric Channel 1 Port 0-3) and rows #2,#1 (Fabric
Channel 2 Port 0-3).
The two following options as described in the ATCA standards PICMG3.1 Rev.1.0 are
supported:
 1x 1000Base-BX or 1000Base-KX (PICMG3.1 Option 1)
 1x 10GBase-BX4 or 10GBase-KX4 (PICMG3.1 Option 9)
4.5.4 ATCA Base Interface and SOL
The redundant Base Interface of the ATCA-8310 is also provided by the Switching Unit. Two
SGMII lanes are connected to a MARVELL 88E6161 switch. This switch has 1000B-T ports to the
Base interface. It is configured at power up via serial prom which allows for immediate SOL after
power up.
4.5.4.1 Serial over LAN
The serial over LAN functionality is provided by a Freescale controller. This device transforms up
to two RS232 ports to Ethernet and is connected to the Base-Switch via 100B-T.
4.6 Timing Synchronization (TS)
To support the timing synchronization on the ATCA-8310 the ACS8520 from Semtech is used.
The Microprocessor Interface Mode Selection connected to the SPI-bus of the Freescale P4080.
