7: Troubleshooting

Boot-Up

The following table explains what the SYSTEM status lights mean during the boot-up process.

UBox 4100: Has three (one green and two red) SYSTEM indicators

UBox 2100:, Has four (one green, two amber and one red).

The green has the same meaning on both units. The UBox 2100's two amber indicators are equivalent to the UBox 4100’s red indicator. The additional red indicator on the UBox 2100 indicates error.
