Installation Guide

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.
There is also a USB console port. If the USB console port is connected, it will be selected over the RJ45
console port.
Cooling
Each base model is available with either front-to-back or back-to-front cooling. There is no operational
dierence between these switch versions.
Switch cooling is provided by six hot-swappable fan modules providing N+1 redundancy. Fan modules
are available in two dierent models that direct the airflow either from front to back or from back to
front. All six installed fan modules must be of the same model, so that they all direct the airflow in the
same direction.
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.
Power Supplies
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.
Note
Air must flow in the same direction for all installed fan modules and power supplies in a
switch.
Note
See the ExtremeXOS 22.6 User Guide and the ExtremeXOS 22.6 Command Reference Guide
for feature-specific information about the switches and for information regarding switch
configuration.
