LINK/ACT LED

orange   10BASE-T
green 100BASE-TX
blue 1000BASE-T (Kurobox HG only)

DISK FULL LED (red)

on Hard drive full
blink   Writing to Flash ROM

DIAG LED (red)

3 times blink   Partition warning: /dev/hda3 is not mounted on /mnt. You can ignore it.
4 times blink Problem with the cooling fan - probably rotor jammed.
5 times blink Problem with Flash ROM*
6 times blink Hard drive not found, or ppc_uartd not running.
7 times blink Problem with the RAM, Ethernet Controller, or IDE Host Controller.
blink many times   Writing to Flash ROM.
* It may be possible to recover from a Flash ROM error by pulling out the power cord and trying to boot again the next day.

Notes: Users have reported problems when the drive already has a Linux partition on it-- the DIAG LED blinks 6 times. The solution appears to be to simply to reformat the drive.
