•No light—System is in the off state (S5, or mechanical (AC power not applied) OFF).

•Solid Amber—System fault, but power supply is good—normal operating state (S0).

•Blinking Amber—System fault error condition including Power Supply (only +5VSB working), Vreg failure, missing or bad CPU.

•Blinking Green—System is in power saving states S1, S3 or S4. (Blink rate is 1Hz). No fault/error condition.

•Solid Green—System is fully functional and is in S0 (ON) state.
