Ensure your device is powered off (optional but recommended for safety).

SFP Port Location

Locate the SFP port on your Cisco device.

Insert Transceiver

Gently insert the Cisco GLC-SX-MMD into the SFP port until it clicks.

Once the transceiver is securely in place, you can power on your device if it was turned off during installation.

3. Connect the Multimode Fiber Cable

After the transceiver is inserted, connect your multimode fiber optic cable (with an LC connector) to the LC port on the Cisco GLC-SX-MMD. Ensure the fiber cable is in good condition and properly connected to both the transceiver and the receiving device (router, switch, server, etc.).
