To remove the module, depress the release mechanism on the port and gently pull the transceiver out.

Recommendations

Ensure the host device firmware and optics compatibility list support third-party SFP28 modules. Use the correct fiber type, cabling and transceiver variant for your required link distance and environment. Handle the transceiver by the housing, keep connectors capped when not in use, and follow electrostatic discharge (ESD) precautions during installation and removal.
