Performance assured AddOn certification test

Testing is really what sets us apart. Our in-house staff of lab technicians have fine tuned our process for over a decade. With a proprietary process, every single product is put through our rigorous specifications, tested to OEM standards as well as physically tested in its intended environment. All product testing and certification is performed exclusively by AddOn, and is not certified by the OEM. We take your exact configuration and recreate it in our lab to guarantee its functionality and performance.

AddOn Data Traveler

Our proprietary Data Traveler System™ creates a living manifest that allows us to uniquely serialize, track, and ship each and every part.

OEM Spec Testing

Our in-house coding facility programs all of our parts to standard OEM specs as well as creating unique, one-of-a-kind coding for customized networking solutions.

Environment Testing

AddOn goes above and beyond the standard to recreate the network environment in which these parts will be used. With all the major manufacturers' switches we can recreate an environment and test each part to guarantee its performance.

Code that makes the difference

Not only are our products put through a rigorous testing method, but each part is also coded in our in-house lab. With advanced firmware and DOM coding, all network transceivers and direct attach cabling are programmed to the OEM specification. We pride ourselves on our programming expertise with the ability to replicate authenticated code.

Custom coding solutions

Most companies won't bother with custom networking solutions. We realize that today's infrastructures can be filled with multiple manufacturers' parts and that at some point they may need to communicate with one another.

At AddOn, we provide custom coding solutions to fit our customers' needs. Our team of experts are ready to provide a full spectrum of service and support.
