Sorry to necro this thread. I have N1548P. "show inventory" and "show inventory media" did not work on my switch.What did work was this. I have eBay generic singlemode 10km transceivers. Despite this, it still shows our wavelength! :) ch-switch#show interfaces te1/0/3 transceiver detailType.............................. UNKNOWNMedia.............................

Hello, I have a couple PowerConnect 5448 switches that are up for replacement.  The both link up to our customers network via fiber GBIC's.  Aside from pulling the GBIC and looking at the model number, is there a way to determine that info from the CLI or web interface? I'd just as soon not take down the network just to gather data. Thanks!
How to find what model / type of GBIC is installed without removing it
