Extreme Networks ExtremeSwitching X440-G2 Series Hardware Installation Manual page 31

Each base model supports front-to-back cooling only. Switch cooling is provided by a replaceable fan
module.
Note
The fan module must be ordered separately.
A serial console port on the front panel of the X450-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.
The non-PoE+ switches (that is, the 24t and 48t models) have a fixed, internal power supply. The PoE+
switches (that is, the 24p and 48p models) have two power supply bays to accommodate AC power
supplies. Power supplies have integrated cooling fans that operate independently of the switch fans.
For more information about the power supplies used in the X450-G2 switches, see
Power Supplies on page 104.
Note
X450-G2 series switches do not support back-to-front (BF) power supplies, and the switches
do not support the back-to-front fan module.
X450-G2 series switches require ExtremeXOS version 16.1.1 or later, or version 21.1.1 or later.
