ExtremeSwitching X690 Series Switches

The X690 series switch provides 10 Gb datacenter aggregation with 100 Gb uplinks, ideally suited for use as a "leaf" switch in conjunction with "spine" switches like the X870 series.

The X690 series switches include the following base models:
Front-panel Ethernet ports can provide 100 Gb Ethernet connectivity using installable QSFP28 and QSFP+ optical modules. The front panel of each X690 switch provides the following:

For details about the port partitioning options that are available on X690 switches, see Partitioning X690 Switch Ports into Data Lanes.

X690 series switches also have 48 front-panel Ethernet ports that can provide 10-gigabit Ethernet connectivity using installable optical modules.

A serial console port on the front panel of the X690 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.

Note

Note

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.

Caution

Caution

Air must flow in the same direction for all installed fan modules and power supplies in a X690 series switch.

X690 series switches require ExtremeXOS version 22.3 or later.

Partitioning X690 Switch Ports into Data Lanes

Front-panel ports on X690 series switches can be configured for either 100-gigabit or 40-gigabit mode, and each port can be partitioned into data lanes through the use of split cables. This yields a total of up to 72 ports.

Port numbers are assigned depending on whether the physical ports are partitioned into data lanes. To illustrate, X690 Ports that Can Be Partitioned into Data Lanes shows the physical ports on the X690 front panel that can be partitioned. Port Number Assignments (in 40 Gb Mode) and Port Number Assignments (in 100 Gb Mode) detail how port numbers are assigned for each of the physical ports.

X690 physical ports that can be partitioned into data lanes

The ports labeled 49-52 and 53-56 operate in 40 Gb mode, acting as single 40 Gb ports or multiple 10 Gb ports.

The ports labeled 57-60 and above operate in 40 Gb mode or 100 Gb mode, with a variety of speeds.

In 40-gigabit mode, each port can be partitioned into four 10-gigabit data lanes.

In 100-gigabit mode, each port can be partitioned into two 50-gigabit data lanes or four 25-gigabit data lanes.
