Front Panel of an EX3300 Switch
The front panel of an EX3300 switch consists of the following components:
•
Network ports:
•
Depending on the switch model, 24 or 48 10/100/1000BASE-T Gigabit Ethernet
ports (ports labeled 0 through 23 or 0 through 47)
•
Power over Ethernet Plus (PoE+) available in all network ports in EX3300-24P and
EX3300-48P models
•
Power over Ethernet Plus (PoE+) not available in any network port in EX3300-24T,
EX3300-24T-DC, EX3300-48T, and EX3300-48T-BF models
•
Four built-in uplink ports:
•
The uplink ports support 1-gigabit small form-factor pluggable (SFP) transceivers,
10-gigabit small form-factor pluggable (SFP+) transceivers, or a combination of
these transceivers.
•
Ports labeled 0 and 1 are, by default, configured as network ports. You can configure
these ports as Virtual Chassis ports (VCPs).
•
Ports labeled 2 and 3 are, by default, configured as VCPs. You can configure these
ports as network ports.
