Determining QFX5220 Optical Interface Support
You can find information about the optical transceivers supported on your Juniper device by using the
Hardware Compatibility Tool. In addition to transceiver and connection type, the optical and cable
characteristics–where applicable–are documented for each transceiver. The Hardware Compatibility Tool
enables you to search by product, displaying all the transceivers supported on that device, or category, by
interface speed or type. The list of supported transceivers for the QFX5220 is located at
https://apps.juniper.net/hct/product/#prd=QFX5220
CAUTION:
If you face a problem running a Juniper Networks device that uses a third-party
optic or cable, the Juniper Networks Technical Assistance Center (JTAC) can help you
diagnose the source of the problem. Your JTAC engineer might recommend that you
check the third-party optic or cable and potentially replace it with an equivalent Juniper
Networks optic or cable that is qualified for the device.
NOTE:
For interoperability with other QFX Series switches, ensure autonegotiation on the QFX5220
is disabled.
