The Summit® X460-G2 series is based on Extreme Networks® revolutionary ExtremeXOS®, a highly resilient OS that providescontinuous 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.
