ExtremeSwitching X590 Series Switches
The X590 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 X690 and X870 series.
The X590 series switches include the following base models:
•
ExtremeSwitching X590-24t-1q-2c Switch Ports and Slots on page 59
•
ExtremeSwitching X590-24x-1q-2c Switch Ports and Slots on page 60
Front-panel Ethernet ports provide 40 Gb and 100 Gb Ethernet connectivity using installable QSFP28
and QSFP+ optical modules, respectively. Each X590 switch has:
•
One QSFP+ based 40 Gb port. With appropriate cabling, the QSFP+ port can be partitioned into
four 10 Gb ports.
•
Two QSFP28 based 100 Gb ports. With appropriate cabling, each of the QSFP28 ports can be
partitioned into 10 Gb, 25 Gb, 40 Gb, or 50 Gb ports.
For details about the port partitioning options that are available on X590 switches, see Partitioning
X590 Switch Ports into Data Lanes on page 58.
Each X590 switch also has 24 front-panel Ethernet ports that provide 10-gigabit Ethernet connectivity.
Connectivity is 100Mb/1 Gb/10GBASE-T for the X590-24t-1q-2c model and 1 Gb/10GBASE-X SFP+ for
the X590-24x-1q-2c model.
A serial console port on the front panel of the X590 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 dierent
models that direct the airflow either from front to back or from back to front.
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.
