The ExtremeSwitching switches are compact enclosures 1.75 inches high (1 U). Each switch model provides between 8 and 72 high-density copper or fiber optic ports operating at speeds up to 40 Gbps. Many models also provide combination copper/fiber uplink ports. PoE connections and options for adding 10-Gbps or 40-Gbps uplink connections are available on some models.
Many ExtremeSwitching switches include high-speed stacking interfaces that allow you to connect up to eight switches into a single SummitStack management entity. Models are available for AC or DC power connection; all switches make provision for redundant power supplies. Most models have connections for optional external redundant power supplies: the Summit X450-G2 (PoE models), X460, X460-G2, X480, X650, X670, X670-G2, and X770 switches provide two bays for pluggable power supplies.
Most models are available in versions that are compliant with the Trade Agreements Act (TAA); these versions are identified by a -TAA suffix on the model number. Functionally, the TAA-compliant models are completely equivalent to the matching versions that are not TAA-compliant. In all feature descriptions, references to a specific Summit switch model also apply to the equivalent TAA-compliant model.
This document describes switches that are supported on ExtremeXOS version 16 and earlier. For information about other ExtremeSwitching and ExtremeSwitching switches, refer to the ExtremeSwitching Hardware Installation Guide for Switches Using ExtremeXOS Version 30.
