Single Pair Ethernet Switch

  • 7L600

The 7L600 ModBlox7™ module is a Single Pair Ethernet (SPE) switch designed for rugged industrial applications. The assembly is provided with seven 100BASE-T1 (IEEE 802.3bw) ports and in addition two 1000BASE-T RJ45 jacks. The SPE connectors conform to the IEC 63171-6 industrial style IP20 mating face.

The 7L600 was designed according to the new PICMG® ModBlox7™ standard for open modular computing. This innovative concept does not require a backplane, and allows either DIN rail or wall mounting, and 19-inch sub-rack box mounting as well.

The 7L600 is equipped with the Marvell® 88Q5072 Automotive Ethernet switch and is configured by default for self-managed operation. Its PHYs are fully inter-operable with the Open Alliance BroadR-Reach® (OABR) standard for automotive connectivity. Via the RJ45 jacks, 7L600 modules can be easily cascaded and connected to the enterprise network.

As an option, the switch module is available with an ARM based mezzanine controller card, suitable e.g. for additional protocol support and switch management, and even custom specific additions.
