Cisco ESR6300 Embedded Series Router

An Embedded router that's ready for action

The Cisco ESR6300 Embedded Series Router enables third party system integrators to build custom Gigabit Ethernet Routing solutions. The ESR6300 is optimized for size, weight and power to fully operate in extreme harsh environments. With Cisco IOS XE, it provides highly secure data, voice, and video communications to stationary and mobile network nodes.

Features and benefits

Exponentially faster

The ESR6300 offers significantly faster crypto throughput than the previous generation of ESRs, to meet increased bandwidth needs from the rapid growth of sensor data and video streams.

Cisco Trustworthy Systems

The onboard Trust Anchor Module (TAM) plus image signing, secure boot, and runtime defenses help ensure that the code running on the Cisco ESR6300 is authentic, unmodified, and operating as intended.

Simplified integration

At 3 inches by 3.75 inches, the ESR6300 is smaller than its predecessors, making it easier to integrate in compact solutions. It is hardened for extreme temperatures, shock and vibration to achieve the highest standard of reliability.

Modularity options

The ESR6300 provides 2 WAN ports of Gigabit Ethernet that give you a choice of media type and 4 LAN ports of Gigabit Ethernet with PoE/PoE+ ready options.  As your needs evolve, add mSATA storage for IOx edge compute.

Streamlined management with IOS-XE

Cisco IOS XE is highly programmable, with open and standards-based APIs and next-generation, multilayer security built in. This unified software stack is ideal for process and workflow automation, so you can qualify and deploy new services faster.

Software-defined WAN on the ESR6300

The ESR6300 is HW ready to support SD-WAN - in the near future you will be able to leverage IT expertise to a distributed network, operate at scale, and lower TCO. Cisco SD-WAN architecture delivers scale, simplicity, and unified management for extending the enterprise network to a distributed IoT deployment.

How you can use it

Defense and aerospace

Deploy ESR6300’s to build advanced tactical networks that provide highly secure and reliable high-speed connectivity. Deliver highly secure broadband for voice, video, and data communication. Integrators can use the 6300 ESR in the communication systems of military hardware in vehicles, aircraft, helicopters, drones, and ships.

Oil and gas

Oil and gas companies need to monitor and analyze data from some of the most remote, harshest environments in the world. Use the ESR6300 to build reliable networks that can monitor high-value assets and collect data for real-time data analysis. Drive efficiencies and increase safety while operating in remote and hazardous locations.


Install the ESR6300 where your applications require high-quality voice, video, and data connectivity: in trains, commercial airplanes, manned, unmanned, self-driving vehicles. Integrators can build routers with custom interfaces and the right level of mechanical ruggedization--ingress protection, temperature, shock vibration--based on application needs.
