Replacing an SFP
The MP Router was designed to work with SFP optical modules. SFPs provide optical connections to
external devices for both SWL and LWL connections. SFPs are replaced using a new pluggable unit,
rather than replacing the MP Router.
For a list of supported SFPs, enter the sfpSupport command.
Time required
Less than 5 minutes.
Items required
• New SFP
• New cable (if necessary)
Procedure
To remove and replace an SFP from an MP Router:
1. Verify that there is no activity by viewing the MP Router LEDs.
For details about LED activity on the MP Router, see ”Interpreting LED activity” on page 51.
2. Remove the cable from the SFP module.
