vLocate LED: Use this blue LED to locate the memory expansion module. The locate LED also has a button that you can press to light up other servers or other memory expansion modules to which the memory expansion module is connected.
vPower supply fault (error) LED: When this amber LED is lit, it indicates a faulty
vMemory error LED: When this amber LED is lit, it indicates a DIMM problem.
vLink error LED: When this amber LED is lit, indicates that a QPI link fault or a EXA link fault has occurred. The port LED for the link that has been disconnected will not be lit on the rear of the memory expansion module. EXA link LEDs are on the rear of the memory expansion module, and the QPI link LEDs are on the server to which the memory expansion module is connected.
vFan error LED: When this amber LED is lit, it indicates a fan error.
vSystem board error LED: When this amber LED is lit, it indicates a memory expansion module
vConfiguration error LED: When this amber LED is lit, it indicates a configuration error. The memory LED might be lit to indicate a memory configuration error.
