Yes, the 0GF76J is a 1Gbs shortwave SFP transceiver. If the connection is functional, you could run the following command and it should suppress those messages. [tag:service] unsupported-transceiver
Hi,  I've a question regarding Dell N2024 switches and 0GF76J transceivers. I bought 2 of this switch model and 4 of this transceiver model from a supplier. The optical fiber ports of this switch are normally SFP+ (10 Gbps). I let the supplier chose the transceivers and he sold me 4 of the 0GF76J model.  When I connected the 2 switches via the 4 SFP ports with a CORNING OPTICAL CABLE 6B MM 50/125 OFNR-PVC 2014 00143M, I noticed the following things: Being in console mode, the following messages appeared: TRAPMGR[trapTask]: traputil.c(735) 255 %% UNSUP_OPTICS: Non-qualified optics in Te1/0/1 TRAPMGR[trapTask]: traputil.c(735) 256 %% UNSUP_OPTICS: Non-qualified optics in Te1/0/2 The color of the Link/SPD Led was solid amber which, according to the user manual, means that the port is operating at 1000 Mbps   I found it strange so I googled 0GF76J. Few information came up but I think that this model of transceiver is a SFP 1 Gbps. That’s the reason I post in this forum, I want to ask these questions: Is the Dell 0GF76J transceiver a SFP 1 Gbps? If yes, I suppose that’s why I got the TRAPMGR messages and the amber light?   Photos of the cabling +  Link/SPD Led: 1 - 2.
