System ready, but degraded: redundancy lost such as PS
or fan failure; one of several DIMMs not ready; non-critical
temperature/voltage threshold
Amber
BLINK
Non-critical failure: critical temperature/voltage threshold;
minimum number fans not present or failed; voltage
regulator overheated
Amber
ON
Critical alarm: CPU 1 missing or failure; voltage fault; no
memory present; BMC/video memory failure
OFF
AC power off; powered down (DC-off state or S5), and no
degraded, non-critical, critical conditions exist*

* When the server is powered down (transitions to the DC-off state or S5), the BMC is still on
standby power and retains the sensor and front panel status LED state established before the
power-down event. If the system status is normal when the system is powered down (the
LED is in a solid green state), the system status LED will be off.
