vLocate LED: When this blue LED is lit, it indicates that the command from the server IMM to the memory expansion module is complete. Use this blue LED to locate the memory expansion module. The front locate LED also has a button that you can press to locate other servers or other memory expansion modules to which the memory expansion module is connected. This LED is functionally equivalent to the locate LED on the front of the memory expansion module.
vSystem error LED: When this LED is lit, it indicates that a system error has occurred.
vQPI ports: Insert either a QPI cable or a filler panel in each of these connectors.
