Instruction Manual

For a description of each LED color and what its state might mean, see Table 39. For a description
of how the blade status LEDs appear under normal conditions, see Table 40.
Table 39 Explanations of blade status LED states
Possible states and explanationsRepresentsLED Color
• Solid off — blade main processor is not operating
(or blade is booting)
• Solid on — blade main processor is not operating
(however, this does not apply to the LMD; solid on
indicates that the LMD main processor is operating
normally)
• Blinks one time every second (1 Hz) — blade main
processor is operating normally
• Blinks 10 times every second (10 Hz) — identify
mode
• Solid on for three seconds, then blinks twice at 1
Hz, and then repeats — blade firmware is down-
loading
Processor statusGreen
• Solid off — blade power and control subsystem is
operating normally
• Solid on — blade power and control subsystem
has failed
Solid on also can mean that the blade power and
control subsystem firmware is autoleveling. In conjunc-
tion 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.
Health statusAmber
• 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

State and ExplanationLED Color
Blinks one time every second (1Hz) — blade main processor is operating
normally (however, this does not apply to the LMD; solid on indicates
that the LMD main process is operating normally)
