Table 41 describes how to interpret the drive sled status LED activity that you might see on the rear
of a drive sled.
Table 41 Drive Sled Status LED States
Possible states and explanations Represents LED color
• Solid off — drive sled main processor is not
operating (or blade is booting)
• Solid on — drive sled main processor is not
operating
• Blinks one time every second (1 Hz) — drive
sled 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 — drive sled or
drive brick firmware is downloading
• Blinks three times in three seconds (1 Hz),
then pauses (solid off), and then repeats —
drive brick is activating (varying on)
Processor status Green
• Solid off — drive sled controller (drive DC
to DC converter [DDC]) is operating normally
• Solid on — drive sled DDC has failed
Health status¨ Amber
• Solid off — drive sled is not receiving power
• Solid on — drive brick is powered down;
ready to be replaced (swap mode) or varied
on
• Blinks one time every 10 seconds (flash) —
drive brick is powered on; operating nor-
mally
Power control status Blue
