# Adding the IAM Role to an Amazon Neptune Cluster
<a name="bulk-load-tutorial-IAM-add-role-cluster"></a>

Use the console to add the IAM role to an Amazon Neptune cluster. This allows any Neptune DB instance in the cluster to assume the role and load from Amazon S3.

**Note**  
The Amazon Neptune console requires the user to have the following IAM permissions to attach the role to the Neptune cluster:  

```
iam:GetAccountSummary on resource: *
iam:ListAccountAliases on resource: *
iam:PassRole on resource: * with iam:PassedToService restricted to rds.amazonaws.com
```
