Connect SFP Modules

Before you begin this task, ensure that you have read and understood the safety warnings in the Safety
Precautions for Module Installation and Removal section of the Safety Warnings chapter.
Use only Cisco SFP modules on a Cisco device. Each SFP module has an internal serial EEPROM that is
encoded with security information. This encoding provides a way for Cisco to identify and validate that the
SFP modules meet the requirements of the device.
Caution We recommend that you wait for 30 seconds between the removal and insertion of an SFP module from the
device. The wait period allows the transceiver software to initialize and synchronize with the device. Changing
an SFP before this wait period could result in transceiver initialization issues that disable the SFP.
