ATCA-7370/ATCA-7370-S Installation and Use (6806800P54H) 108
5.6 Ethernet Ports
5.6.1 ATCA 3.0 Base Interface
The dual Base interface of the ATCA-7370 Node board is from two ports of Intel I350 quad ports
Gigabit Ethernet Controller. The device offers quad 10/100/1000Base-T and quad 1000Base-X
interfaces. A serial EEPROM is used for storage of configuration parameters such as the MAC
addresses.
The two 10/100/1000Base-T interfaces of the Intel I350 are directly connected to the
transformers and providing the ATCA Base interface on connector P23 rows #5 and #6 (Node
Board). This redundant connection provides the Dual-Star Base Interface configuration
required according to ATCA 3.0 specification (Base Interface is always Dual Star
10/100/1000Base-T).
5.6.2 Fabric Interface ATCA 3.1
The ATCA-7370 Fabric Interface is provided by Intel 82599 (Niantic). It is in accordance to ATCA
subsidiary specification 3.1 Ethernet for ATCA Systems. Either two10GBase-BX4 or two
1000Base-BX Ethernet interfaces are connected to the fabric channel #1 and #2 in the Zone 2
providing support for ATCA 3.1 Option 1 and 9.
 Option 1 (one 1000Base-BX on Port 0 of the fabric channels 1,2)
 Option 9 (one 10GBase-BX4 on Port 0-3 of the fabric channels 1,2)
The two 10GBase-BX4 and the two 1000Base-BX interfaces are connected to the ATCA
backplane's Fabric Interface on connector P23 rows #4,#3 (Fabric Channel 1 Port 0-3) and rows
#2,#1 (Fabric Channel 2 Port 0-3)
5.6.3 Faceplate Ethernet Ports
The ATCA-7370 provides two RJ45 on its front panel for Gigabit Ethernet. The RJ45-0 (the
upper one on front panel) can support 10/100/1000 BASE-T ethernet. The RJ45-1(the lower
one on front panel) share the same controller in I350 with update channel GE interface. The
update channel is active currently, so the RJ45-1 is reserved and cannot been used now.
