LED Description
Power LED (green)
| on | Normal operation. |
| blink | Bootup, prior to Flash ROM update, and ppc_uartd starting. |
| blink slowly | Shutdown timer has been activated. Box will shutdown soon. |
If ppc_uartd does not start for some reason (or is started late due to hardware/software issues), the Power LED will continue blinking. After five minutes the DIAG LED will continuously blink 6 times (hard drive failure) and then shut the box down.
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. |
| multiple blinks | 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.
