## Extreme Conditions Call for Extreme Durability
“Durable” takes on a whole new meaning for electronic systems that are exposed to extreme and repeated changes in temperature, like those experienced by military aircraft between takeoff and landing.
X-ES has designed and manufactured a wide range of embedded computing solutions capable of withstanding these high levels of thermal and mechanical stress, including many products built to VITA 47 C4 specifications.

### Rising to the Challenge of VITA 47 C4
Electronic components have a higher risk of failure when exposed to extreme temperatures—particularly when the temperature alternates repeatedly from hot to cold, a scenario known as thermal cycling.
The VITA 47 specification, an ANSI standard for rugged plug-in units in embedded systems, defines non-operating temperature and thermal cycling requirements for several environmental classes. The C4 class has the widest temperature range and requires the highest durability performance.
X-ES has delivered VITA 47 C4 durability-rated products to industry-leading defense and aerospace contractors, and we continue to develop products that support this standard. Relevant product families include Intel® and NXP processor boards as well as XMC networking modules.
### Specialized Design and Manufacturing
Building products that withstand these conditions requires specialized hardware design and manufacturing. We have expertise in several cutting-edge techniques for enhancing the durability of electronic components and assemblies, including underfill, staking, and unique printed circuit board (PCB) design techniques.
All products are assembled at our in-house manufacturing facility, ensuring fast turnaround and giving us more flexibility to accommodate changes throughout the design and development process.
We also have an in-house environmental testing facility equipped with state-of-the-art thermal test chambers. To ensure compliance with environmental requirements, all VITA 47 C4 products are tested in accordance with MIL-STD-810 and MIL-STD-202.

## Upgrade Path for End of Life Cisco 5915 and Cisco 5940 Embedded Services Routers
 /  / **Upgrade Path for End of Life Cisco 5915 and Cisco 5940 Embedded Services Routers**
## XChange6300 Points the Way Forward
For customers facing discontinued support for the Cisco 5915 and Cisco 5940 Embedded Services Routers (ESRs), the  bare‑metal router from X-ES is an ideal replacement for all your Cisco IOS-XE® networking and communications needs.
#### Maximize Networking Performance
The XChange6300 ESR is a conduction-cooled XMC/PMC router card that can plug into existing sockets or be used in standalone applications. Like the end-of-life Cisco routers, the XChange6300 extends Cisco’s industry-leading Mobile Ready Net technology to provide highly secure data, voice, and video communications to stationary and mobile network nodes across wired and wireless links. The XChange6300 can operate as a standalone Layer 3 router or bring Layer 3 capability to X-ES’ line of rugged managed Layer 2 embedded Ethernet switches, enabling a Layer 2 and Layer 3 single-slot solution.
!
## Rugged and Mission-Ready
X-ES has differentiated the XChange6300 from other ESRs by designing the most rugged solution in the industry for Cisco IOS-XE® functionality. The XChange6300 boasts advanced ruggedization features and support, including leaded solder assembly to mitigate tin whiskering, ensuring persistent, mission-critical routing functionality in even the harshest environments. X-ES engineers can also offer configuration options to support unique project requirements, such as parylene conformal coating for added protection.
#### Long Lifecycle Support
The XChange6300 is also backed by X-ES’  process, which proactively monitors for components that are about to be discontinued and then offers the customer notifications, impact assessments, and the option for last-time buys of the obsolete component. Designed for customers with long product runways, X-ES offers the XChange6300 as a logical, dependable way to transition off the EOL Cisco 5915 and Cisco 5940 ESRs.
