CompactPCI® Serial • 20-Port Gigabit Ethernet Switch

The SL4-TUBA is a peripheral slot card for CompactPCI® Serial systems. The board is equipped with a modular Gigabit Ethernet switch fabric up to 20 ports. While 5 GbE ports are wired to associated RJ45 front panel jacks, another 14 GbE ports are available for rear I/O via the backplane connectors P5/P6.
In addition, the SL4-TUBA is provided with a PCI Express® to Gigabit Ethernet controller, which is internally also connected to the GbE switch.
For optimum scalability, the SL4-TUBA employs up to four Gigabit Ethernet switches internally, wired together for a total of 20 GbE ports. The Marvell® 88E6350R devices in use are self-managed and comprise a rich feature set.
Likewise, the Intel® I210-IT Ethernet NIC provides latest networking technology, e.g. Audio-Video Bridging (AVB) for tightly controlled media stream synchronisation, buffering, and reservation. The SL4-TUBA is equipped with a maximum of four Marvell® 88E6350R Gigabit Ethernet switches. Each of them provides 5 ports with integrated Ethernet transceivers (PHY) and two digital interfaces (RGMII). The switches are coupled together by means of their RGMII interfaces. A total of 20 PHY ports is available on-board, wired to the front panel (5) and to the CompactPCI® Serial backplane connectors P5/P6 (14). One PHY port is connected to the on-board Gigabit Ethernet controller.
While the front panel RJ45 jacks are provided with integrated magnetics, all other GbE PHY ports are isolated by on-board magnetics modules. A custom specific backplane will be required for usage of the rear I/O GbE ports.
The SL4-TUBA can be inserted into any CompactPCI® Serial peripheral slot. A single PCI Express® lane would be sufficient for communication with the on-board Gigabit Ethernet controller.
