Juniper EX-Series

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 was launched 12 years after the company's founding in 1996.[5]

Models and platforms

EX2200

The Juniper EX2200 line of 1Gb Ethernet switches are compact gigabit switches. They are small and energy efficient making them environmentally friendly and great for office use. PoE variants in the EX2200 family support high-power 802.3at PoE+ (up to 30W/port) on all ports, up to a maximum of 405 Watts, which is the maximum power budget for the switch. The power budget is the lowest of all EX series PoE switches, and notably insufficient to run high-power Powered Devices (PD's) on all ports simultaneously. 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. The 4 SFP ports allow 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 compact, affordable, and energy efficient switch in a 1 U high and 10.8 inch wide formfactor. 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. Even the PoE version is fanless. The EX2200-C is a small 19" rack mountable (using optional brackets) or desktop switch with 12 gigabit ports with a choice of PoE or non-PoE. The switch also has 2 SFP uplink ports for virtual chassis (stacking), link aggregation or as uplinks to aggregation switches. The EX2200-C has a data rate of 28 Gbit/s.[6]

EX2300

The Juniper EX2300 series is the successor to EX2200. In addition to the features of the EX2200 the most notable feature is the four SFP ports being updated to SFP+ ports. EX2300 is compatible with the Juniper Fusion concept.

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 (Gbit/s) throughput (full duplex) in a 1 rack-unit (RU) footprint. 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. The EX2500 reached End of Sale in late 2012[7]

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

Juniper's EX3300 Ethernet switches are cost-effective enterprise access solutions for data center environments that support converged data, voice, and video. Models come with 24 or 48 10/100/1000BASE-T ports and four GbE/10GbE SFP/SFP+ uplink ports.The EX3300 switches support IEEE 802.3af Power over Ethernet (PoE) or 802.3at PoE+. Optimized for the data center, the switches offer front-to-back and back-to-front cooling options, and can be configured with a DC power supply. Up to 10 EX3300 switches can be interconnected and operated as a single device using Juniper’s Virtual Chassis technology.

EX3400

The Juniper EX3400 series is the successor to EX3300. In addition to the features of the EX3300 it adds two 40 G QSFP+ ports and two slots for power supplies instead of the fixed PSU in the EX3300. EX3400 is compatible with the Juniper Fusion concept.

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. All EX4200 family switches support power over Ethernet (PoE). The T series supports 802.3af PoE (up to 15.4W/port) on a subset of ports. The PX series switches support 802.3at PoE+ (up to 30W/port) on all ports. The total PoE power budget varies between models.

EX4300

Successor of the EX4200, and similar in functionality/options. Can be used in as a leaf in a leaf and spine topology with the QFX5100. Also complies to new ECC regulations which appears to be one of the reasons the EX4200 is being replaced.

EX4500

The Juniper EX4500 series consists of 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]

EX4550

The EX4550 series can be seen as an intermediate model between the EX4500 and the EX4600 with more similarities to the EX4500 since it is not an ELS switch.

EX4600

Fixed platform. Virtual Chassis configuration consisting of up to 10 switches. Backplane 960 Gbit/s. EX4600 Ethernet Switches offer a compact, highly scalable, high-performance 10GbE solution for enterprise campus distribution deployments as well as low-density data center top-of-rack environments.

Designed to help organizations grow into higher density campuses, the EX4600 provides deployment flexibility, high availability using unified in-service software upgrades (unified ISSU), and management simplification with support for MC-LAG. The highly flexible, high-density EX4600 supports up to 72 1 GbE ports, 72 10 GbE ports, or 12 40 GbE ports through installable modules, delivering 1.44 Tbit/s of Layer 2 and Layer 3 connectivity in a single rack unit.

EX4650

Featuring 48 wire-speed 10GbE/25GbE small form-factor pluggable and pluggable plus transceiver (SFP/SFP+/SFP28) ports and 8 wire-speed 40GbE/100GbE quad SFP+ transceiver (QSFP+/QSP28) ports in a compact 1 U platform, the EX4650 provides the flexibility to support mixed 1GbE, 10GbE, 25GbE, 40GbE, and 100GbE environments. The EX4650 Ethernet Switch offers a compact, highly scalable, high-performance 10/25/100GbE solution for midsized to large enterprise campus distribution deployments.[9]

EX6200

Juniper's EX6200[7] Ethernet switch is a scalable, resilient, high-performance wiring closet solution for campus deployments, or for end-of-row access in the data center. The flexible, 14RU, 10-slot chassis reserves two slots for holding redundant Switch Fabric Routing Engine (SRE) modules, while eight slots are dedicated for 48-port 10/100/1000BASE-T line cards. One redundant SRE can be replaced by an additional line card for higher port densities. Two line cards are available, one with and one without support for IEEE 802.3af Power over Ethernet (PoE) and 802.3at PoE+. The EX6200 comes with additional Layer 2 and Layer 3 features in the base image, including IPv6 support*, Quality of Service (QoS), and great scalability for MAC and IP addresses.

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]

EX9200

Juniper's EX9200[10] line of programmable Ethernet switches simplifies the deployment of cloud applications, server virtualization and rich media collaboration tools in campus and data center core and aggregation environments.In the campus, the EX9200 enables collaboration and provides simple and secure access for the delivery of mission-critical applications. In the data center, it simplifies operations to align the network with fast-changing business requirements.Three EX9200 switches are available:

  • The EX9204 (4 slots in a 6RU chassis)
  • The EX9208 (8 slots in an 8RU chassis)
  • The EX9214 (14 slots in a 16RU chassis)

The EX9200 chassis deliver up to 240 Gbit/s (full duplex) per slot. A pass-through mid-plane design supports capacity of up to 13.2 Tbit/s for built-in migration to next-generation deployments. Any combination of GbE, 10GbE and 40GbE interfaces can be used, and the switches include support for 100GbE cards when available.

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.[11] 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.[12]

gollark: Anything can be an OISC if you just make the one instruction "execute"!
gollark: We should use 0 bit posits. The great thing about them is that you could fit infinity of them in an array.
