EX4200 VirtualReproductionChassis T chnology
The Juniper Networks EX4200 Eth rnet Switches with virtual chassis technology combine the high availability and carrier-class reliability of modular systems with the economics and flexibility of stackable platforms, delivering a high-performance, scalable solution for data center, and campus and branch office environments.
forUp to 10 EX4200 switches can interconnect using virtual chassis technology to create a single l gical device supporting up to 480 10, 100, or 1000BASE-T ports or 240 100BASE-FX 1000BASE-X ports, plus an additional 40 Gigabit Ethernet or 20 10-Gigabit Ethernet uplink ports. Different models can mix in a virtual chassis
c n igurati n to provide a variety of port and density options.

FlexibleReproductionUplink Modul s
You can deploy a single 24-port or 48-port switch initially; as requirements grow, Juniper Networks virtual chassis technology allows up to 10 EX4200 switches to interconnect over a 128 Gbps backplane, which you can manage as a single device,
fordelive ing a scalable, pay-as-you-grow solu for expanding network environments. Flexible Gigabit Ethernet and 10-Gigabit Ethernet uplink options enable high-speed connectivity to aggregation-layer or core-layer switches which connect multiple floors
buildings.
Redundant Power and Cooling
Not All EX4200 switches include high availability features such as redundant, hot-swappable internal power supplies and field-replaceable, multi-blower fan trays to ensure maximum uptime. In addition, the base EX4200 switch models offer Class 3 Power over Ethernet (PoE), delivering 15.4 watts on the first eight ports to support networked devices such as telephones, video cameras, and wireless LAN (WLAN) access points for low-density converged networks. Full PoE options delivering
15.4 watts on all 24 or 48 ports are also available, making them ideal for high-density IP telephony deployments.
JUNOS Software
The EX4200 switches leverage the modular JUNOS Software, ensuring consistent implementation and operation.

Fixed ConfigurationReproduction
The EX3200 fixed-configuration switches from Juniper Networks offer a high-performance standalone solution for access-layer deployments in branch and remote offices as well as campus networks.
forUplink Modules
The EX3200 line also supports optional 4 port Gigabit Ethernet and 2 port 10-Gigabit Ethernet uplink modules with pluggable optics to provide high-speed connectivity to aggregati n-layer switches or other upstream devices.
Modular Power and Cooling
Featuring complete Layer 2 and Layer 3 switching capabilities, the EX3200 switches satisfy the wiring closet connectivity requirements of today’s high-performance businesses. Four platform configurations are available offering 24 and 48 10, 100, and 1000BASE-T ports with either full or partial PoE. The base 24-port and 48-port EX3200 switches deliver a full 15.4 watts of Class 3 PoE on the first eight ports for supporting networked devices such as telephones, video cameras and WLAN access points in converged networks. The EX3200 switches with full PoE deliver 15.4 watts on all 24 or 48 ports to support high-density IP telephony and other converged network environments.

JUNOS Software
The EX3200 switches run the same JUNOS Software used by Juniper Networks routers to power the world’s largest and most complex networks.
By utilizing a common operating system, Juniper Networks delivers a consistent implementation and operation of control-plane features across all products—functions
rangingReproductionfrom chassis management to Spanning Tree to OSPF. To maintain that consistency, the JUNOS Software adheres to a highly disciplined developme process
that utilizes a single source code, follows a single quarterly release trai , a d employs a highly available modular architecture that prevents isolated failures from bri gi g an entire system down.

JUNOS Software
The SRX Series runs on the proven JUNOS Software which is based on a modular design offering a single-source operating system for the network. Unlike any other product on the market, it provides one operating system, enhanced through one release, and developed based on a single modular architecture.

SRX3400Reproductionand SRX3600 Modules
The SRX3600 and SRX3400 support comm form-factor modules (CFM). A single-wide module format and a double-wide module format are available. All single-wide CFMs can insert in any single-wide slot in the front and rear of the chassis.
forSimila ly, all double-wide CFMs can insert in any double-wide slots. DPC, SPC, and Netwo k Processing Card (NPC) modules are in single-wide CFM format. The SCB, the RE, and the CB are not in CFM format, and thus have assigned slots within the
chassis. With the interchangeability among DPC, SPC, and NPC, you have more
flexibility and scalability when deploying your networks based on the requirements in the field. For example, if you need more ports and a bigger oversubscription ratio, then
y u can load more slots with DPCs; on the other hand, if you need a smaller Not oversubscription ratio for better QoS behavior, or if you need more security services,
then you can load more slots with SPCs. With this arrangement, only the onboard network interface ports are in use. SRX5600 and SRX5800 cards are not interchangeable with SRX3400 and SRX3600 cards.
