Note:
• Discard SFPs according to all local laws and regulations.
• SFPs can be installed and replaced without disabling the Ethernet interfaces.
• SFPs are keyed to prevent incorrect insertion. If an SFP is not seated properly, remove
it and confirm that the orientation is correct before reinserting it.
