| | Some additional LED behavior is possible when the drives are managed |
| | by a RAID controller: |

Note This LED behavior is possible only when the server has the optional SAS Expander installed. It does not occur with the standard SAS Extender.
•Amber, blink rapidly in unison—The Locator option has been enabled on an LSI MegaRAID 9260-8i RAID controller. The LEDs on the drives that are managed by the controller blink in unison.
