There is no need to do anything else other than plug the fiber in and remove the Ethernet cable. It will auto start communicating with each other, no other commands or steps needed. Thanks.
Looking for suggestions on connecting my two PC 5448 switches together using Fiber instead of Ethernet. I have one 5448 in a closet where all of my LAN drops terminate into my patch panel. I have the other PC 5448 mounted in my cabinet along with my servers. Currently I have a single CAT5 cable running between the two switches. I have ordered the following from Dell so I can connect the 2 switches together with fiber instead of the single CAT5. 1 SFP 1000SX TRANSCEIVER, PowerConnect (no cables included), Cust Kit LC/LC LSZH Simplex 9/125 Single-Mode Yellow Fiber Patch Cable - 49.21 ft  Will I need to do anything special on each switch to make this work? All I intend to do is remove the current CAT5 cable connecting the 2 switches together and replacing it with the new fiber.  Thanks
