SFP Transceiver Modules for CISCO Catalyst 4948 Switch

Asked by visibleworld in Network Routers, Network Switches & Hubs, Optical Networking

Tags: CISCO Catalyst 4948 Switch

I have : Finisar, Avago, Trendnet and one brand-less module and they don't seem to work.

After I plug in the module to any of the SFP ports (45-48) it blinks Amber continuously. Ports are configured to use SFP as media type and they are administratively turned on.

I'm thinking the SFP modules must be bought from CISCO.
What are the supported brands for this switch.

Any help appreciated.
