ATCA-9405 Installation and Use (6806800M71G) 96
The four Slave SMI Interfaces (CPU_SMI) for host access to all address mapped entities in the
Switch are not used on ATCA-9405. The PCI Express interface is used instead.
5.3 Base Interface
The redundant (dual) ATCA base interface is provided by the Ethernet Switch. The physical
1000Base-T interface (according to PICMG3.0) is implemented using one Marvell 88E1322
Integrated 10/100/1000 Dual Gigabit Ethernet Transceiver.
Two SGMII lanes of the Ethernet Switch are connected to the PHY device. Basic Ethernet PHY
configuration after power-up is done using hardware strapping options. After power-up the
PHY is managed by the Switch via MII interface.
5.4 Fabric Interface
The redundant (dual) ATCA fabric interface is provided by the Ethernet Switch. The physical
interface is implemented using two Marvell 88X2241 10Gbps Quad Channel Transceivers.
The two 88X2241 Transceivers provide eight ports (4 ports each) that are directly connected
to Zone 2 connector P23 row 4+3 (Fabric Channel 1, Port 0-3) and connector P23 row 2+1
(Fabric Channel 2, Port 0-3).
The 88X2241 devices are connected to the Ethernet Switch using ports XLG10 and XLG26. For
more information, refer
Ethernet Switch on page 91 .
Configuration of the 88X2241 device is done via its MDIO/MDC interface which is connected
to the Ethernet Switch. Fabric Channel 1 Transceiver is connected to MXSMI1 (XLG26)
interface. Fabric Channel 2 Transceiver is connected to MXSMI0 (XLG10) interface.
