Meaning
In EX4300 switch model numbers:
• The 24T, 24P, 32F, 48T, and 48P in the model number indicate the type of network ports on the
switch:
• 24T—The switch has 24 10/100/1000BASE-T Ethernet network ports.
• 24P—The switch has 24 10/100/1000BASE-T Ethernet network ports with all ports equipped for
Power over Ethernet (PoE+).
• 32F—The switch has 32 1-Gigabit SFP network ports.
• 48T—The switch has 48 10/100/1000BASE-T Ethernet network ports.
• 48P—The switch has 48 10/100/1000BASE-T Ethernet network ports with all ports equipped for
PoE+.
• AFI indicates that the switch is shipped with two fan modules and a power supply, each bearing an
AIR IN (AFI) label. Switches that do not have AFI in their model numbers ship with two fan modules
and a power supply, each bearing an AIR OUT (AFO) label.
The labels on the fan modules and the power supplies indicate the direction of airflow they provide
within the chassis when installed in the switch. AIR IN (AFI) labels indicate back-to-front airflow, and
AIR OUT (AFO) labels indicate front-to-back airflow.
• The DC in the model number indicates that the switch model works on DC power supply. Switches
that do not have DC in their model numbers work on AC power supply.
