Link fault LED (amber)

When this amber LED is lit, it indicates that the link through the SAS cable
is not successful.

Link up LED (green)

When this green LED is lit, it indicates that the link through the SAS cable
is successful.

Service Action Allowed (blue)

This LED is supported only when the EXP3800 is attached to a DCS3860
controller. Do not remove the ESM unless this blue LED is lit.

Fault LED (amber)

When this amber LED is lit, it indicates that the ESM has failed.

Power-on LED (green)

When this green LED is lit, it indicates that the ESM is receiving power.
