Summit Switches

The Summit 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 Summit 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 Summit switches, refer to the ExtremeSwitching and Summit Switches: Hardware Installation Guide for Switches Using ExtremeXOS 21.1 or Later.
