32-Port EX4300 Switches
The 32-port EX4300 switches—EX4300-32F and EX4300-32F-DC—provide 32 built-in 1-Gigabit
Ethernet small form-factor pluggable (SFP) network ports that can house SFP transceivers, four built-in
10-Gigabit Ethernet small form-factor pluggable plus (SFP+) ports that can house SFP+ and SFP
transceivers, and two built-in quad small form-factor pluggable plus (QSFP+) ports that can house 40-
Gigabit QSFP+ transceivers. They support power supply and fan module with front-to-back airflow
direction and have a slot for installing an optional uplink module—a 2-port 40-Gigabit Ethernet QSFP+
uplink module (model number: EX-UM-2QSFP) that can house two QSFP+ transceivers or an 8-port 10-
Gigabit Ethernet SFP+ uplink module (model number: EX-UM-8X8SFP) that can house eight SFP+
transceivers, eight SFP transceivers, or a combination of SFP and SFP+ transceivers in the eight ports on
the uplink module.
