Actions Based on LED States
When the RAS system is operating properly, service actions should be based on tickets first and foremost.
However, some situations occur when the amber LED indicates problems that are not detected by the ticket
system. You should always act on any amber LED that is solidly on, which indicates that the blade’s power
and control subsystem has failed. In this case, replace the blade.
When you replace a blade FRU or escalate a problem based on LED states, perform the following steps:
1 Observe and report the timing pattern of the blue, amber, and green LED group. Spend at least 30
seconds observing the LEDs and record the results in the service request (SR) and on any equipment
failure report form that is returned with the part. Proper reporting of all LED states is critical for
determining the root cause of the failure.
2 Capture a system snapshot and send it to technical support for analysis.
Amber Health status • Solid off — blade’s power and control subsystem is
operating normally
• Solid on — blade’s power and control subsystem has failed
Solid on also can mean that the blade’s power and control
subsystem firmware is autoleveling. In conjunction with the
blue amber LED blinking one time every 10 seconds, this is
a normal condition. Autoleveling takes about three minutes
for each blade, and blades within an I/O management unit
autolevel in series. It can take as long as three minutes for
the power and control subsystem to download. Never
remove a blade when the amber LED is solid on unless it has
been on continuously for at least 10 minutes.
Blue Power control status • Solid off — blade is not receiving power
• Solid on — blade is powered down; ready to be replaced
(swap mode)
• Blinks one time every 10 seconds (flash) — blade is powered
on; operating normally
Table 17 Explanations of Blade Status LED States Under Normal Conditions
LED Color State and Explanation
Green Blinks one time every second (1 Hz) — blade’s main processor is operating normally
(however, this does not apply to the LMD; solid on indicates that the LMD’s main
process is operating normally)
Amber Solid off — no errors are detected; blade’s power and control subsystem is operating
normally
Blue Blinks one time every 10 seconds (flash) — blade is powered on; operating normally
