# Replace faulted SFP

Unisphere for PowerMax supports a small form-factor pluggable component (SFP) replacement policy. This policy specifies whether it is the customer or Customer Support that is responsible for the replacement of SFPs.

## Prerequisites

See Roles and associated permissions to determine the user roles that can perform this task.

This task applies to storage systems running PowerMaxOS 10.2.0 that support a customer replaceable small form factor pluggable component (SFP) replacement policy (see View Storage System details).

The SFP replacement procedure occurs in response to an automatic SFP part and email dispatch.

## About this task

| NOTE: If the SFP replacement is not successful or if a user attempted stop of an in-progress replacement occurs, the lock in SymmWin is kept by the replacement process. The result of this lock is that other SymmWin processes cannot be run. You must contact Customer Support to resolve this issue.

## Steps

1. Select the storage system.
2. Select System > Physical View.
3. Click Replace Faulted SFPs
4. Select the faulted SFP to be replaced.
5. Click Run Now
6. Read the warning concerning SFP replacement and click OK to proceed.
7. On the CRU Replacement Instructions dialog, perform the tasks that are listed in the Replacement Instructions section.
   If you decide that you do not want to proceed with the replacement, click Stop Replacement. You can go to the Job List View to view the progress of the SFP replacement task and also stop an in-progress replacement.
8. Select the slider next to the Export button to zoom in and out on the hardware view.
9. Click Export to export the contents of the dialog to a .jpg file.
10. Go to the Job List View to monitor the status of the SFP replacement task.
11. When the Job List View gets updated to indicate that the SFP replacement task has been successful, go back to the Replace Faulted SFPs dialog and click Mark as Completed.

    You can also click Mark as Completed from the Job List View after it gets updated to indicate that the SFP replacement task has been successful.

    | NOTE:

    If the SFP replacement is not successful or if a user-attempted stop of an in-progress replacement occurs, the lock in SymmWin is kept by the replacement process. The result of this lock is that other SymmWin processes cannot be run. You must contact Customer Support to resolve this issue.
