How to resolve “This transceiver is not certified by Fortinet”
When using Fortinet brand equipment with third-party transceivers, you may have experienced that the transceivers do not work properly and, when digging deeper into the problem, you are “greeted” with the following error message: “This transceiver is not certified by Fortinet“:
Or, perhaps you may have encountered the following error:
So, what could cause such issues?
Common connectivity problems with Fortinet equipment may be attributed to using low-quality, non-certified transceivers. Thanks to our extensive experience in the field of optical transceivers, we have found that such problems are caused by using modules with improper coding. While most transceivers adhere to standard MSA coding guidelines, with popular brands such as Fortinet, it is not that simple. Fortinet have implemented usage of special coding bytes to flag and identify certified or non-certified transceivers. The implementation of such coding rules, as Fortinet claims, ensure that proper and correct modules are used to ensure reliable data flow and to eliminate any guesswork when selecting the required products.
Unfortunately in Fortinet case, there is no “magic solution” in terms of CLI commands to fix such issues. For example you can use allow unsupported transceiver Aruba and use service unsupported-transceiver and no errdisable detect cause gbic-invalid commands in Cisco devices to allow switch to ignore wrong Part ID`s in the optical module coding and surpress the alarms. Instead in Fortinet case, you are required to either recode the transceivers to Fortinet compatible code or purchase fully compatible Fortinet modules to stay clear of such faults.
Luckily, that is where we can help you! We have accumulated vast experience in module coding and ensuring compatibility across a wide range of brands including Fortinet, for whom we have made a lot of deliveries. Additionally, we have a dedicated Fortinet compatibility page where you can look up Fortinet-compatible modules you need.
