How to Deal With Unsupported Transceiver Errors

Transceiver errors are never welcomed by designers, but when they arise, they have to be ready to respond. This may require some research on the designer’s behalf to determine how to handle unsupported errors. Manufacturers may have some tips on how to handle these errors, but there are some frequent recommendations that seem to work for most designers who need to know how to address these issues. Here are our suggestions.

What to Do When You Receive an Unsupported Transceiver Error
Depending on the message you receive, there are several ways to address unsupported transceiver errors. For instance, if you receive this error, “3750e-sw1(config)#service unsupported-transceiver [1],” you should consider whether the error was a result of customer installation or if it was a defective product. If the product is defective, consider contacting someone who can help with the warranty.

Most error messages arise when the device has not been certified. If the third-party device has not been sourced from a channel partner, other problems may arise also. Solving the router issue is not always easy. It often requires a transceiver of the same manufacturer as the router to address the issue. This is often the only way to resolve the issue. Although, many designers have used “hack codes” to force the devices to work.

Keep in mind that there are also hidden commands on some of the devices, and error messages will appear, “service unsupported transceiver.” Luckily, there is an option that will “allow other transceivers.” It is up to the designers to determine if there is a fault or defect that can be traced to the use of the third-party transceivers.

If there is a third-party error, sometimes the only resolution is to remove the device entirely. However, it’s best to explore the other options before taking this course of action. It will allow you to take advantage of the significant savings that third-party transceivers provide.

Some manufacturers will not support any transceiver that’s not certified. Thus, if you have an unsupported device from someone other than a channel partner, you’ll have to isolate the router problem until you discover the issue. You may also have the logistical challenge of having another support agreement with your transceiver vendor, which may need to be resolved.

Benefits of Third-Party Transceivers
The primary benefit is the cost savings. The difference in price often exceeds 30 percent or more. Because transceiver costs are a significant part of the total system cost, it is important for designers to minimize these costs. With the significant savings, designers can re-invest and make their designs better.

Most transceiver vendors would have a support agreement to handle defective transceivers. If you order from your network equipment manufacturer, it should be included. Though not all switch vendors will manufacture the transceivers, there are some that will. This is preferable to many designers because the likelihood of compatibility is increased.

Dealing With Unsupported Transceiver Errors
Keep in mind that they level of testing required will depend on the type of transceiver and the system. Minimal testing requirements are usually desired, but the primary goal is to ensure that each transceiver complies with IEEE and MSA standards to avoid unsupported transceiver errors. As long as the recommendations are followed, most problems should be resolved in a short period of time. Know the hidden commands and make your best judgment call for the best results.
