Extreme Networks Summit X670-G2 Series X670-G2-48x-4q-FB-AC-TAA - Switch - L3 - Managed - 48 x SFP+ + 4 x QSFP+ - front to back airflow - rack-mountable - TAA Compliant Extreme Networks | 17310T

The Summit X670-G2 product family provides high-density 10 Gigabit Ethernet and 40 Gigabit Ethernet switching in a small 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-G2-48x-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.

• Flexible stacking over 40 Gigabit Ethernet
  The Summit X670-G2-48x-4q supports high-speed stacking using QSFP+ ports, which is ideal for demanding applications where a high volume of traffic traverses through the stacking links, yet bandwidth is not compromised through stacking.
• Intelligent switching and MPLS / H-VPLS support
  Summit X670-G2 supports sophisticated and intelligent Layer 2 switching, as well as Layer 3 routing including policy-based switching / routing, Provider Bridges, bidirectional ingress and egress Access Control Lists, and bandwidth control both for ingress and egress. To provide scalable network architectures used mainly for Carrier Ethernet network deployment, Summit X670-G2 supports MPLS LSP-based Layer 3 forwarding and Hierarchical VPLS (H-VPLS) for transparent LAN services. With H-VPLS, transparent Layer 3 networks can be extended throughout the Layer 3 network cloud by using a VPLS tunnel between the regional transparent LAN services typically built by Provider Bridges technology.
• Precision Time Protocol (PTP)
  Summit X670-G2 offers Boundary Clock (BC), Transparent Clock (TC), and Ordinary Clock (OC) for synchronizing phase and frequency and allowing the network and the connected devices to be synchronized down to microseconds of accuracy over Ethernet connection.
• Audio Video Bridging (AVB)
  The X670-G2 series supports Audio Video Bridging to enable reliable, real-time audio / video transmission over Ethernet. AVB technology delivers the quality of service required for high-definition and time-sensitive multimedia streams.
• Low-latency switching for cluster computing
  Summit X670-G2 can achieve latency in an extra short amount of time and supports cut-through switching for latency-sensitive cluster computing.
• Low power consumption
  The Summit X670-G2 series is designed to be environmentally green. System power consumption is very low at both highload and idle situations through the power-efficient hardware design. The power supplies are also highly efficient, which minimizes the loss of power and unnecessary heat generated by the power supply. Summit X670-G2 series switches can be used in AC or DC powered environments.
