You must have an installed network module to use the transceiver modules. See the switch release notes on Cisco.com for the list of supported pluggable transceiver modules. Use only supported pluggable transceivers on the switch. For the latest information about supported transceiver modules, refer to the Cisco Transceiver Modules Compatibility Information.

For information about installing, removing, cabling, and troubleshooting pluggable transceiver modules, see the module documentation that shipped with your device.

Observe these precautions:

Warning

Do not remove the dust plugs from the pluggable transceiver modules or the rubber caps from the fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the module ports and cables from contamination and ambient light.

Removing and installing a pluggable transceiver module can shorten its useful life. Do not remove and insert any module more often than is necessary.

To prevent ESD damage, follow your normal board and component handling procedures when connecting cables to the switch and other devices.

When you insert several pluggable transceiver modules in multiple switch ports, wait for 5 seconds between inserting each module. This will prevent the ports from going into error disabled mode. Similarly, when you remove a pluggable transceiver module from a port, wait for 5 seconds before reinserting it.
