The 61.42 identifier is what the port map and the ordering sheet key on, so the module carries that exact designation in the EEPROM data Arista hosts verify at insertion. DDM/DOM diagnostics are supported for in-service monitoring of the optic once the link is live. Conformance to the SFP MSA is checked per unit, together with identity and cleanliness inspection. The GreenLights4Life® Limited Lifetime Replacement Warranty backs every module sold.
