EX3200 Switches Hardware Overview
Juniper Networks EX Series Ethernet Switches provide scalable connectivity for the enterprise market, including branch offices, campus locations, and data centers. The switches run the Juniper Networks Junos operating system (Junos OS), which provides Layer 2 and Layer 3 switching, routing, and security services. The same Junos OS code base that runs on EX Series switches also runs on all Juniper Networks J Series, M Series, MX Series, and T Series routers.
EX3200 Switches
Juniper Networks EX3200 Ethernet Switches provide connectivity for low-density environments. Typically, you deploy these switches in branch environments or wiring closets where only one switch is required.
EX3200 switches are available in models with either 24 or 48 ports and with either all ports equipped for Power over Ethernet (PoE) or only 8 ports equipped for PoE. EX3200 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
Uplink Modules
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.
Power over Ethernet (PoE) Ports
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.
