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.
PoE is defined in the IEEE 802.3af standard. In this standard, the amount of power that
can be supplied to a powered device is limited to 15.4 W. Starting with Junos OS Release
11.1, EX3200 switches support enhanced PoE, a Juniper Networks extension to the IEEE
302.3af PoE standard that permits up to 18.6 W per PoE port.
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.

The EX3200 switch is available with 24 or 48 ports with partial or full Power over Ethernet
(PoE) capability. EX3200 switches with a DC power supply installed do not provide PoE.
