Non-Juniper SFP+/SFP modules not detected in any port of an EX2300-24P but fine in an EX2300-48P

While staging an EX2300-48P and an EX2300-24P (both Junos 18.2R3-S5.3) with non-Juniper SFP+/SFP moules, the 48-port switch recognised the transceivers and created interfaces, but the 24-port switch showed nothing in any of its four uplink ports; show chassis hardware listed PIC 1 as 4x10G SFP/SFP+…

CBS350 SFP-10G-LR link only comes up when the TX fiber is inserted before RX; faulty transceiver pair

While rolling out single-mode fiber between Cisco CBS350-8MGP-2X switches (firmware 3.4.0.17) with SFP-10G-LR modules, the poster hit strange behaviour: the link only comes up if the duplex LC connector is split and the TX fiber is inserted first, then the RX fiber. Inserting the joined LC…
