Interpreting LEDs

For a description of each LED color and what its state might mean, see
Tab l e 8 on page 94. For a description of how the blade status LEDs
appear under normal conditions, see Tab l e 9 on page 95.
Table 8 Explanations of Blade
Status LED States
LED Color Represents Possible States and Explanations
Green Processor status • Solid off — blade’s main processor is not operating (or
blade is booting)
• Solid on — blade’s main processor is not operating
(however, this does not apply to the LMD; solid on
indicates that the LMD’s main processor is operating
normally)
• Blinks one time every second (1 Hz) — blade’s 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 downloading
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
