ExtremeSwitching X670-G2 Series Switches

The X670-G2 series switches have 48 or 72 front-panel Ethernet ports that can provide 10-gigabit Ethernet connectivity using installable SFP+ optical modules. In addition, the X670-G2-48x-4q series switches offer four QSFP+ ports.

The X670-G2 series switches include the following base models:

Each base model is available with either front-to-back or back-to-front cooling. There is no operational difference between these switch versions.

The X670-G2-48x-4q and X670-G2-72x have SFP+ ports that support dual interface speeds of Gigabit Ethernet and 10-gigabit Ethernet. SFP+ ports can accept both gigabit SFP and 10 gigabit SFP+, and depending upon the pluggable optics you choose, SFP+ ports can work in both modes.

The front panel of the X670-G2-48x-4q switch also provides four QSFP+ based 40 Gb ports. With appropriate cabling, each of the four QSFP+ ports can be partitioned into four 10 Gb ports.

A serial console port on the front panel of the X670-G2 series switch allows you to connect a terminal and perform local management. An Ethernet management port can be used to connect the system to a parallel management network for administration. Alternatively, you can use an Ethernet cable to connect this port directly to a laptop to view and locally manage the switch configuration. The Ethernet management port supports 10/100/1000 Mbps speeds.

Switch cooling is provided by replaceable fan modules. Fan modules are available in two different models that direct the airflow either from front to back or from back to front. All installed fan modules must be of the same model, so that they all direct the airflow in the same direction.



Ensure that all fan module slots are filled when the switch is powered on. Fan modules can be hot-swapped after power has been turned on.

Two power supply bays accommodate either AC or DC power supplies. Power supplies have integrated cooling fans that operate independently of the switch fans. Like the fan modules, the power supplies are available in models with either front-to-back or back-to-front cooling airflow.



Air must flow in the same direction for all installed fan modules and power supplies in a X670-G2 series switch.

X670-G2 switches offer Boundary Clock (BC), Transparent Clock (TC), and Ordinary Clock (OC) for synchronizing phase and frequency and allowing the network and the connected devices to be synchronized over Ethernet connections. Precision is +-2 nanoseconds (ns) with time accuracy +50 to -65 ns.

X670-G2 series switches require ExtremeXOS version or later, or version 21.1.1 or later.



See the ExtremeXOS 30.7 User Guide and the ExtremeXOS 30.7 Command Reference Guide for feature-specific information about the switches and for information regarding switch configuration.
