The Summit® X460-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 X460-G2 switches are effective campus edge switches that support Energy Efficient Ethernet (EEE – IEEE 802.3az) with IEEE 802.3at PoE-plus and can also serve as aggregation switches for traditional enterprise networks. The Summit X460-G2 series is also an option for DSLAM or CMTS aggregation, or for active Ethernet access.

The Summit X460-G2 can also be used as a top-of-rack switch for many data center environments with features such as high-density Gigabit Ethernet for concentrated data center environments; XNV™ (ExtremeXOS Network Virtualization) for centralized network-based Virtual Machine (VM) inventory, VM location history and VM provisioning; Direct Attach™ to offload VM switching from servers, thereby improving performance; high-capacity Layer 2/Layer 3 scalability for highly virtualized data centers; and intra-rack and cross-rack stacking with industry-leading flexibility.

Flexible Port Configuration

Summit X460-G2 offers flexible port configurations. For Summit X460-G2 24 port copper models with 10Gb uplinks with four dedicated Gigabit Ethernet fiber ports and four shared Gigabit Ethernet fiber ports, the switch can have up to 8 fiber GbE ports, while still providing 20 Gigabit Ethernet copper ports (PoE-plus or non-PoE). The Summit X460-G2 24 port copper models with 1Gb uplinks can provide up to 12 SFP ports with 20 Gigabit Ethernet ports or eight SFP ports with 24 copper GbE ports.

All models come equipped with either 4 ports of SFP+ 10 GbE or 4 ports of SFP 1GbE resident on the faceplate of each model. Through an optional VIM slot, Summit X460-G2 switches can be equipped with an additional 2 ports of 10 GbE for a total of six 10 Gigabit Ethernet ports on the 10Gb uplink models.

As another option, each unit can be equipped with 2 ports of QSFP+ 40 Gigabit Ethernet for uplinks or stacking.

High-Performance Stacking

Up to eight Summit X460-G2 switches can be stacked using three different methods of stacking: SummitStack, SummitStack-V, and SummitStack-V160.

Summitstack - Stacking Using Copper CX4 Connections

The Summit X460-G2 supports SummitStack by using the Summit X460-G2-VIM-2ss module, which offers high-speed 40 Gbps stacking performance and provides compatibility with the Summit X440, X460, X460-G2 and X480 stackable switches running the same version of ExtremeXOS.

Summitstack-V - Flexible Stacking Over 10GbE

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 40 Gbps stacking connectivity of up to 40 km while reducing the cable complexity of implementing a stacking solution. SummitStack-V is compatible with Summit X440, X460, X460-G2, 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.

Note: Stacking will NOT be supported on the 10GbE fiber VIM and the 10GbE copper VIM with initial X460-G2 shipments.

Note: SummitStack-V is NOT supported on the 1GbE (SFP) front panel faceplate ports of non-10Gb X460-G2 models.

Summitstack-V160 - Flexible Stacking Over 40GbE

The Summit X460-G2 also supports high-speed 160 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-V160 can support passive copper cable (up to 3m), active multi-mode fiber cable (up to 100m), and QSFP+ optical transceivers for 40 GbE up to 10km. With SummitStack-V160, the Summit X460-G2 provides a flexible stacking solution inside the data center or central office to create a virtualized switching infrastructure across rows of racks. SummitStack-V160 is compatible with Summit X460-G2, X480, X670V, X670-G2 and X770 switches running the same version of ExtremeXOS.

Intelligent Switching and MPLS/H-VPLS Support

Summit X460-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.

To provide scalable network architectures used mainly for Carrier Ethernet network deployment, Summit X460-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 (IEEE 802.1ad) technology.

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 PoE-plus standard expands upon Power over Ethernet by increasing the power limit up to 30 watts, and by standardizing power negotiation by using LLDP. Summit X460-G2 supports IEEE 802.3at PoE-plus and supports standards-compliant PoE devices today and into the future.

1588 Precision Time Protocol (PTP)

Summit X460-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 X460-G2 series supports IEEE 802.1 Audio Video Bridging to enable reliable, real-time audio/video transmission over Ethernet. AVB technology delivers the quality of service required for today’s high-definition and time-sensitive multimedia streams.

Ordering Notes

The X460-G2 base switches do not ship with fan trays or power supplies. The fan tray and power supplies must be ordered separately as well as any of the optional VIMS. There is only one optional VIM slot on each X460-G2 switch. The optional Timing Module has a separate dedicated slot on the back of the X460-G2 switch.
