switches with a DC power supply installed do not provide PoE. All models provide ports
that have 10/100/1000Base-T Gigabit Ethernet connectors and optional 1-gigabit small
form-factor pluggable (SFP) transceivers, 10-gigabit small form-factor pluggable (SFP+)
transceivers, or 10-gigabit small form-factor pluggable (XFP) transceivers for use with
fiber connections.
EX3200 switches include:
A field-replaceable power supply and an optional additional connection to an external
power source.
A field-replaceable fan tray with single fan.
Junos OS with its modular design that enables failed system processes to gracefully
restart.
EX3200 switches have these features:
Run Junos OS for EX Series switches
Have options of 24-port and 48-port models
Have options of full (all ports) or partial (8 ports) Power over Ethernet (PoE) capability
Have optional uplink modules that provide connection to distribution switches
Optional uplink modules are available for all EX3200 switches. Uplink modules provide
two 10-gigabit small form-factor pluggable (XFP) transceivers, four 1-gigabit small
form-factor pluggable (SFP) transceivers, or two 10-gigabit small form-factor pluggable
(SFP+) transceivers. You can use XFP, SFP, or SFP+ ports to connect an access switch
to a distribution switch.
PoE ports provide electrical current to devices through the network cables so that separate
power cords for devices such as IP phones, wireless access points, and security cameras
are unnecessary. EX3200 switches with an AC power supply installed have options of
full (all 24 or 48 ports) or partial (8 ports) PoE capability. EX3200 switches with a DC
power supply installed do not provide PoE.
Full PoE models are primarily used in IP telephony environments. Partial PoE models are
used in environments where, for example, only a few ports for wireless access points or
security cameras are required.
