How to Install the Transceiver
Follow these steps to properly install the module:
1. Power Safety Check
- Ensure the switch or router port supports QSFP28 100G modules before installation.
2. Remove Dust Caps
- Remove the protective cap from the transceiver and the LC fiber connector to avoid contamination.
3. Insert the Module
- Gently slide the module into the QSFP28 port until it clicks and locks.
4. Connect the Fiber Cable
- Connect the duplex LC single-mode fiber cable to the module.
5. Verify the Connection
- Use the device CLI or network management interface to verify detection.
- Example Cisco CLI command:
- show interface transceiver details
6. Test Link Status
- Confirm the interface status:
- show interface status
If the link is up and optical power values appear, installation is successful.
