ports, four
SFP+ ports,
and two
QSFP+ ports
You can use the built-in QSFP+ ports as network ports or as VCPs to connect the switch in a Virtual Chassis
or a VCF. By default, the built-in QSFP+ ports are configured as VCPs. You can also use the uplink module
ports to connect members of a Virtual Chassis or a VCF across multiple wiring closets by configuring these
ports as VCPs. For more information about Virtual Chassis, see Understanding EX Series Virtual Chassis. For

48-Port EX4300 Switches

The 48-port EX4300 switches EX4300-48T and EX4300-48P provide 48 built-in 10/100/1000BASE-T
Ethernet network ports, with or without PoE+ depending on the switch model, and four built-in quad small
form-factor pluggable plus (QSFP+) ports that can house 40-Gigabit QSFP+ transceivers. All network ports
in the EX4300-48P switch are equipped for Power over Ethernet (PoE+), whereas EX4300-48T has no
PoE+ ports. These switches support AC or DC power supply with different airflow directions. Each switch
provides a slot for installing an optional 4-port 10-Gigabit Ethernet SFP+ uplink module (model number:
EX-UM-4X4SFP), which has four SFP+ ports that can house four SFP+ transceivers, four SFP transceivers,
or a combination of SFP and SFP+ transceivers in the four ports on the uplink module.
The 48-port EX4300 switches with multigigabit ports—EX4300-48MP and EX4300-48MP-S—provide 24
built-in 10/100/1000BASE-T Ethernet network ports, 24 built-in 100/1000/2500/5000/10000BASE-T
Ethernet network ports, and four built-in Virtual Chassis Ports (VCPs) that house 40-Gbps quad small
form-factor plus (QSFP+) transceivers. The 24 built-in 10/100/1000BASE-T Ethernet network ports
support 10 Mbps, 100 Mbps, and 1 Gbps speeds. The 24 built-in 100/1000/2500/5000/10000BASE-T
Ethernet network ports support 100 Mbps, 1 Gbps, 2.5 Gbps, 5 Gbps, and 10 Gbps speeds. All network
ports are equipped for PoE+ and provide up to 95 watts of power. The four VCPs can be used to connect
the switches to other devices in a Virtual Chassis configuration.
These switches support AC power supply with front-to-back airflow.
Each switch provides a slot for installing an optional 2-port 40-Gigabit Ethernet QSFP+/100-Gigabit
Ethernet QSFP28 uplink module (model number: EX-UM-2QSFP-MR) or a 4-port 1-Gigabit
Ethernet/10-Gigabit Ethernet SFP+ uplink module (model number: EX-UM-4SFPP-MR). The 2-port
