Product highlights

The Cisco® ESR6300 Embedded Series Router is a high-performance, ruggedized router designed for use in harsh environments, offering reliable operation in extreme temperatures and under shock and vibration conditions typical for mobile applications in rugged terrain. With onboard hardware encryption, the Cisco ESR6300 offloads encryption processing from the routing engine to provide highly secure yet scalable video, voice, and data services for mobile and embedded outdoor networks. The router offers high performance, six Gigabit Ethernet interfaces (two routed and four switched), and a rich Cisco IOS® XE Software feature set, providing investment protection for customers deploying bandwidth-intensive applications in mobile or embedded networks in heavy industrial, public safety, transportation, defense, and energy markets.

The Cisco ESR6300 is an embedded router module with a compact form factor of 3.0 by 3.775 in. (76.2 by 95.885 mm). This module may fit in an enclosure that was originally designed for PC/104 modules with some additional adaptation. The more compact design simplifies integration and enables the module to be used in a wide variety of embedded applications. The ESR6300 card is available with a custom-designed cooling plate, as well as without the cooling plate for systems integrators who want to design their own thermal solution. The card is designed as a replacement for the Cisco 5915 and 5940 Embedded Services Routers.

Cisco has an ecosystem of partners and systems integrators that embed Cisco ESR6300s into industry-standard, commercially available enclosures as well as custom enclosures tailored to the unique environments in which these routers are deployed. Figures 1 and 2 show the Cisco ESR6300 NCP (no cooling plate) and ESR6300 CON (conduction-cooled) models, respectively.

Product overview

Table 1.        Key features and benefits



Gigabit Ethernet interface support

The Cisco ESR6300 provides 2 routed and 4 switched high-speed Gigabit Ethernet interfaces, enabling the router to serve as an aggregation point for on-demand network connectivity in mobile or fixed deployments.

Onboard hardware acceleration

The onboard hardware encryption module offloads packet encryption and decryption from the routing engine to increase router performance.

Cisco trustworthy technologies

The onboard Trust Anchor module (TAm), along with image signing, Secure Boot, and runtime defenses, helps ensure that the code running on the ESR6300 hardware platform is authentic, unmodified, and operating as intended.

Storage capabilities

The third-party systems integrator has the option to add an mSATA that Cisco has specified to enhance Cisco IOx edge compute capabilities.

Power over Ethernet-ready architecture

To enable PoE or PoE+, the third-party systems integrator has the option to add a PoE/PoE+ controller based on Cisco’s specifications.

Flexible integration into solutions

The inclusive and compact design of the ESR6300 simplifies integration.

  Non-conduction-cooled and conduction-cooled models are available to satisfy diverse operational environments.
  Designed as a transitional replacement for the Cisco 5915 and 5940 Embedded Services Routers, the ESR6300 allows for accelerated time to market.

The router enables development of solutions that address size, weight, power, price, performance, and cooling requirements.


Enterprise-grade Cisco IOS XE routing and switching security features help ensure highly secure voice, video, and data communication.

Cisco Unified Communications Manager Express support

This application supports up to 48 phones for remote IP telephony on vehicles or in outdoor locations. It provides primary or backup telephony services for command-and-control communications.

Throughput tiers

Various throughput licenses are available:

  50-Mbps encrypted (Default license)
  250-Mbps encrypted (Performance license)
  350-Mbps encrypted (Boost license)

Ease of management

On-premises and cloud-based network management solutions cater to businesses across multiple industries. Tools such as Cisco DNA Center, Cisco IOx, and Cisco vManage* simplify deployment and offer broad cross-network management and the depth of multilayer visibility.

The Network Essentials license offers the essential elements of routing and security necessary for typical IoT deployments. The Network Advantage license enables advanced features, including Multiprotocol Label Switching (MPLS) for a highly scalable and cost-effective solution, mobile IP for seamless migration between networks, and application-aware QoS policies for built-in intelligence.

A single Cisco IOS XE universal image encompassing all functions is delivered with the product. Software feature licenses are preinstalled in the factory, depending on the selection made at the time of purchase, simplifying software delivery and decreasing the operational costs of the deployment. Licenses can be upgraded after deployment by going through the Cisco Smart License activation process.
