ExtremeSwitching X620 Series Switches
The X620 switches are compact 10 Gb Ethernet switches for 10 Gb edge applications with a small, one
rack-unit (1 RU) form factor.
X620 switches support 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.
The X620 series switches include the following base models:
• ExtremeSwitching X620-8t-2x switch
• ExtremeSwitching X620-10x switch
• ExtremeSwitching X620-16p switch
• ExtremeSwitching X620-16t switch
• ExtremeSwitching X620-16x switch
The X620-16p switch requires ExtremeXOS version 22.2.1 or later. Other X620 switch models require
ExtremeXOS version 21.1.1 or later.
X620 Stacking
Up to eight X620 switches can be stacked using SummitStack-V. Each X620 unit can use two
designated SFP+ interfaces for stacking. Standard 10 Gb Ethernet Optics and passive and active cables
can be used in the SFP+ ports for stacking X620 switches using SummitStack-V.
ExtremeXOS supports the SummitStack-V capability using two of the SFP+ ports on the faceplate as
stacking ports, enabling the use of standard cabling and optics technologies used for 10 GbE SFP+.
SummitStack-V is compatible with X440-G2, X450-G2 with 10 Gb uplinks, X460-G2 with 10 Gb uplinks,,
and X670-G2 switches running the same version of ExtremeXOS. SummitStack-V enabled 10 GbE ports
must be physically direct-connected.
Additional X620 Features
All X620 switch models have:
• One 10/100/1000BASE-T RJ45 port implemented as an RJ45 connector.
