Introduction
The Lenovo Flex System Fabric EN4093R 10Gb Scalable Switch provides unmatched scalability, port flexibility, and performance. The switch also delivers innovations to help address several networking concerns today and provides capabilities that help you prepare for the future.
This switch can support up to 64x 10 Gb Ethernet connections while offering Layer 2/3 switching, in addition to OpenFlow and "easy connect" modes. It installs within the I/O module bays of the Flex System™ Enterprise Chassis. This switch can help clients migrate to a 10 Gb or 40 Gb Ethernet infrastructure, offers cloud-ready virtualization features (such as Virtual Fabric and VMready®), and is Software Defined Network (SDN) ready.
Transceivers and cables
With the flexibility of the EN4093R switch, customers can use the following connectivity technologies:
For 1 GbE links, customers can use RJ-45 SFP transceivers with UTP cables up to 100 meters. Customers that need longer distances can use a 1000BASE-SX transceiver, which can drive distances up to 220 meters with 62.5 µ multi-mode fiber (OM1) and up to 550 meters with 50 µ multi-mode fiber (OM2), or the 1000BASE-LX transceivers that support distances up to 10 kilometers with single-mode fiber (1310 nm).
For 10 GbE links (on external SFP+ ports), customers can use SFP+ direct-attached copper (DAC) cables for in-rack cabling for distances up to 7 meters or SFP+ active optical cables (AOCs) for distances up to 20 meters. These cables have SFP+ connectors on each end, and they do not need separate transceivers. For distances up to 30 meters, the 10GBASE-T SFP+ transceiver can be used with Category 6a or 7 RJ-45 UTP cables. For longer distances, the 10GBASE-SR transceiver supports distances up to 300 meters over OM3 multimode fiber or up to 400 meters over OM4 multimode fiber. The 10GBASE-LR transceivers can support distances up to 10 kilometers on single mode fiber.
Warranty
The EN4093R carries a 1-year, customer-replaceable unit (CRU) limited warranty. When installed in a supported chassis, these I/O modules assume your system’s base warranty and any warranty service upgrade.
