Network switches Extreme networks

24x10/100/1000BASE-T PoE, 8x100/1000BASE-X unpopulated SFP (4 SFP ports shared with 10/100/1000BASE-T ports), slot for optional XGM3 module(s), slot for optional stacking module, AC PoE PSU with one unpopulated PSU slot, Fan module, ExtremeXOS Edge license The Summit® X460 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, non-blocking 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 switches are effective campus edge switches with IEEE 802.3at PoE-plus and can also serve as aggregation switches for traditional enterprise networks. The Summit X460 series is also an option for DSLAM or CMTS aggregation, or for active Ethernet access.

The Summit X460 is 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 industryleading flexibility.

High Performance Switching and Routing

- 52-port, 48-port or 28-port Gigabit Ethernet (GbE) connectivity in a 1RU form factor
- Optional two-port 10 GbE in Slot A to provide 20 Gbps uplinks
- Optional four-port 10 GbE in Slot B to provide 40 Gbps uplinks
- Optional in Slot B is Voice-grade SummitStack™ 40 Gbps or SummitStack-V80 80 Gbps high-speed stacking or SummitStack-V, longer distance stacking
- Flexible IEEE 802.3at Power over Ethernet Plus (PoE-plus) to meet the growing demand of converged network applications
- Advanced Layer 2/Layer 3 switching and MPLS/H-VPLS support

Comprehensive Security Management

- User policy and host integrity enforcement, and identity management
- Universal Port Dynamic Security Profiles to provide fine granular security policies in the network
- Threat detection and response instrumentation to react to network intrusion with CLEAR-Flow Security Rules Engine
- Denial of Service (DoS) protection and IP security against man-in-the-middle and DoS attacks to harden the network infrastructure

Flexible Port Configuration

Summit X460 offers flexible port configurations. For Summit X460-24t/24p, 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). If higher density copper ports are required, the switch can provide up to 24 Gigabit Ethernet copper ports while providing 4 Gigabit Ethernet fiber ports. Through the two option slots, Summit X460 switches can be equipped with up to six 10 Gigabit Ethernet ports and two stacking ports. For stacking, depending upon the needs for bandwidth across the units in a stack, Summit X460 supports 40 Gbps SummitStack or 80 Gbps SummitStack-V80 stacking option modules as well as SummitStack-V on the 10GbE ports.

SummitStack-V – Flexible Stacking
Over 10 Gigabit Ethernet

ExtremeXOS supports the new SummitStack-V capability to utilize 10 GbE ports as stacking ports, enabling the use of standard cabling and optics technologies used for 10 GbE such as XFP, SFP+, 10GBASE-T and XENPAK. 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, X450e, X450a, X460, X480, X650, X670 and X670V switches running the same version of ExtremeXOS. SummitStack-V enabled 10 GbE ports must be physically direct-connected.

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 supports IEEE 802.3at PoE-plus and supports standards compliant PoE devices today and into the future.
