Juniper EX-Series is a series of Ethernet network switches designed and manufactured by Juniper Networks.[1][2][3] These switches run on Juniper's network operating system, JUNOS.[4] Juniper's then CEO and present Chairman, Scott Kriens said that the product launch marked the beginning of a transcending chapter in Juniper's history, declaring, "The switch is on". The EX series switch was launched after 12 years since the start of the company in 1996.[5]
Models and Platforms
The Juniper EX series switches includes eight different models: EX2200, EX2500, EX3200, EX3300, EX4200, EX4500, EX6200 and EX8200
EX2200
The Juniper EX2200 line of 1Gb Ethernet switches are compact gigabit switches. They come in a variety of forms including a 24 port plus 4 SFP PoE and non-PoE, a 48 port plus 4 SFP PoE and non-PoE, and the EX2200-C which is a 12 port plus 2 SFP Poe and non-PoE models. These switches are small and energy efficient making them environmentally friendly and great for office use. They also have 4 SFP ports for link aggregation and uplink to aggregation switches without sacrificing the base ports. This model does not have dual power supplies. However, as of September 24, 2012 (JunOS 12.2R1 release date), it supports Juniper's virtual chassis technology. The EX2200-24T/24P has a data rate of 56 Gbit/s while the EX2200-48T/48P has a data rate of 104 Gbit/s.[6]
EX2200-C
The Juniper EX2200-C is a new product in the EX2200 product line of Ethernet switches. These switches are also compact, affordable, and energy efficient. The EX2200-C does not have dual redundant power supplies nor does it have fans and instead the small unit stays cool with a heat sink that sits on the back of the unit. The EX2200-C is a small rack mountable or desktop switch with 12 gigabit ports that can either by PoE or non-PoE. The switch also has 2 SFP uplink ports for link aggregation or as uplinks to aggregation switches. With the compact size and silent operator of this switch it is ideal for deployment in the office or even in a classroom environment. The EX2200-C has a data rate of 28 Gbit/s.[6]
EX2500
The Juniper EX2500 line of 10Gb Ethernet switches address high-performance server access requirements with twenty-four 10 GbE SFP+ ports that deliver wire-speed performance and 700 nanosecond latency. The EX2500 Series will support 480 Gigabit per second (Gbps) throughput (full duplex) in a 1 rack-unit (RU) footprint. The EX2500 Series is expected to be available in 2Q 2009.[7] The EX2500 Series has both power and fan redundancy as standard features. The EX2500 Series comes with dual, load-sharing power supplies, as well as redundant, variable-speed fans to protect from single power supply or fan failure. The EX2500 is a rebranded OEM product which does not run JunOS. Its technical configuration, performance and physical case style is similar to the Blade Network Technologies RackSwitch G8124.
EX3200
The Juniper 3200 switches are 24-port or 48-port boxes with 10/100/1000 Mbit/s Ethernet ports supporting power over Ethernet (PoE). They can also support 1G Ethernet and 10G Ethernet uplinks.[2]
EX3300
EX4200
The Juniper 4200 series is built on modular chassis used for data centers and large corporate offices. They also come in 24-port and 48-port models and support PoE as well as 1 Gig Ethernet and 10Gig Ethernet uplinks. They also have a 24-port fiber option.[2] These switches are stackable, and 10 of them can be linked to create a single virtual switch supporting up to 480 10/100/1000 Ethernet ports, forty 1G Ethernet or twenty 10G Ethernet ports. EX4200 Virtual Chassis can be expanded by using optical ports and/or ethernet ports (VCE - Virtual Chassis Expansion), thus allowing to manage device as a single switch even if locations are separated. Optical modules support up to 80 kilometers range.
EX4500
The Juniper EX4500 series consists models which differ in the direction of the airflow used for cooling and the support for Converged Enhanced Ethernet. All models are two rack units high and have forty 10G Ethernet SFP+ ports. Two slots are available which can be used to add four 10G Ethernet SFP+ ports per slot. The roadmap for these switches includes the ability to stack them together and with switches of the EX4200 series.[8]
EX6200
EX8200
The Juniper 8200 series are core switches for 10G Ethernet backbones that comes in two models. One has an eight-slot 1.6 Tbit/s chassis that supports up to 64 ports. The other has a sixteen-slot 3.2 Tbit/s chassis that supports up to 128 ports. Separate external routing engine XRE200 can be used to offload switches REs.[2]
Features
The EX switches support a range of features including high availability and network access control (NAC). The NAC support, which Juniper calls Unified Access Control (UAC), enables the switches to enforce access policies rather than rely on firewalls, VPN gateways or switches made by other vendors.[2]
Juniper Networks EX-series Ethernet switches are compliant with Internet protocol (IP) telephony solutions from Avaya.[9] They are also interoperable with leading network management platforms from AlterPoint, CA, EMC, HP, IBM, InfoVista and SolarWinds.[4]
Network World Lab Alliance certified that Juniper switches a credible alternative for enterprise access in switching in comparison with other vendors' access switches.[10]
