The Summit X670-G2 product family provides high density 10 Gigabit Ethernet and 40 Gigabit Ethernet switching in a small 1RU form factor. With its versatile design, the Summit X670-G2 provides high density Layer 2/3 10Gb networking with low latency cut-through switching, and IPv4 and IPv6 unicast and multicast routing to enable enterprise aggregation and core backbone deployment in AC-powered and DC-powered environments. The Summit X670-G2 simplifies network operation with the ExtremeXOS modular operating system (OS), which is used among all Extreme Networks Summit and BlackDiamond Ethernet switches. The high availability ExtremeXOS operating system provides simplicity and ease of operation through the use of one OS everywhere in the network. The Summit X670-G2 comes in two models: X670-G2-48x-4q - 48 ports of 1/10Gb SFP+ with 4 ports of 10/40Gb QSFP+ X670-G2-72x - 72 ports of 1/10Gb SFP+ in 1 RU form factor The Summit X670-G2-48x-4q supports four QSFP+ ports of 40 GbE. Each 40 Gigabit Ethernet port can be independently configured as 40 Gigabit Ethernet or 4 x 10 Gigabit Ethernet. The X670-G2-72x model supports 72 ports of native 1Gb/10Gb SFP+ ports in a single compact system without the requirement to use break-out cables to achieve high density 10Gb connections.
