pluggable (SFP+) transceivers, or 10-gigabit small form-factor pluggable (XFP)
transceivers for use with fiber connections.
Additionally, a 24-port model provides 100Base-FX/1000Base-X SFP ports. This model
is typically used as a small distribution switch.
All EX4200 switches have dedicated 64-Gbps Virtual Chassis ports that allow you to
connect the switches to each other. You can also use optional uplink module ports to
connect members of a Virtual Chassis across multiple wiring closets.
To provide carrier-class reliability,EX4200 switches include:
•
Dual redundant power supplies that are field-replaceable and hot-swappable. An
optional additional connection to an external power source is also available.
•
A field-replaceable fan tray with three fans. The switch remains operational if a single
fan fails.
•

GRES (graceful Routing Engine switchover) and nonstop active routing.
•
Junos OS with its modular design that enables failed system processes to gracefully
restart.
Uplink Modules
Optional uplink modules are available for all EX3200 and EX4200 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. Youcan use XFP,SFP, or SFP+ ports to
connect an access switch to a distribution switch or to interconnect member switches
of a Virtual Chassis across multiple wiring closets.
Power over Ethernet (PoE) Ports

power cordsfor devicessuch as IP phones, wireless access points, and security cameras
are unnecessary. Both the EX3200 and EX4200 switches have options of full (all 24 or
48 ports) or partial (8 ports) PoE capability.
Full PoEmodels areprimarily usedin IPtelephony environments.PartialPoE models are
used in environments where, for example, only a few ports for wireless access points or
security cameras are required.
