The Summit X450-G2 series is based on Extreme Networks revolutionary ExtremeXOS, a highly resilient OS that provides continuous uptime, manageability and operational efficiency. Each switch offers the same high-performance, nonblocking hardware technology, in the Extreme Networks tradition of simplifying network deployments through the use of common hardware and software throughout the network. The Summit X450-G2 switches are effective campus edge switches with IEEE 802.3at PoE-plus. The Summit X450-G2 series is also an option for DSLAM or CMTS aggregation, or for active Ethernet access.

Summitstack-V - flexible stacking over 10 gigabit Ethernet
ExtremeXOS supports the SummitStack-V capability using 2 of the native 10 GbE ports on the faceplate as stacking ports, enabling the use of standard cabling and optics technologies used for 10 GbE SFP+, SummitStack-V provides long-distance stacking connectivity of up to 40 km while reducing the cable complexity of implementing a stacking solution. SummitStack-V is compatible with Summit X440, X450-G2 switches with 10Gb uplinks, X460, X460-G2 with 10Gb uplinks, X480, X670, X670V, X670-G2 and X770 switches running the same version of ExtremeXOS. SummitStack-V enabled 10 GbE ports must be physically direct-connected.
Summitstack-V84 - high-speed stacking over dedicated stacking ports
The Summit X450-G2 also supports high-speed 84 Gbps stacking, which is ideal for demanding applications where a high volume of traffic traverses through the stacking links, yet bandwidth is not compromised through stacking. SummitStack-V84 is supported over passive copper QSFP cables (up to 7m). SummitStack-V84 is only supported on Summit X450-G2 switches running the same version of ExtremeXOS.
Intelligent switching
Summit X450-G2 supports sophisticated and intelligent Layer 2 switching, as well as Layer 3 IPv4/IPv6 routing including policy-based switching/routing, Provider Bridges, bidirectional ingress and egress Access Control Lists, and bandwidth control by 8 Kbps granularity both for ingress and egress.
IEEE 802.3AT POE-PLUS IEEE 802.3af
Power over Ethernet has been widely used in the campus enterprise edge network for Ethernet-powered devices such as wireless access points, Voice over IP phones, and security cameras. Ethernet port extenders such as Extreme Networks ReachNXT 100-8t can also utilize PoE, making installation and management easier and reducing maintenance costs. The newer IEEE 802.3at PoEplus standard expands upon Power over Ethernet by increasing the power limit up to 30 watts, and by standardizing power negotiation by using LLDP. Summit X450-G2 supports IEEE 802.3at PoE-plus and supports standards-compliant PoE devices today and into the future.
