Server UID LED
The UID LED is used to locate a particular server when it is deployed in a dense rack with many other servers. Activating the UID LED allows an onsite technician to quickly identify a server for maintenance tasks.
Authorized users can remotely toggle the UID LED on and off using the IPMI tool. When activated through IPMItool, the UID LED will continue to flash blue until it is turned off again in IPMItool.
