Identifying Problems Using Status LEDs
Identifying Problems Using Status LEDs
Your Netfinity 5000 server has LEDs to help you identify problems with some
server components. These LEDs are part of the diagnostics built into the Netfinity
5000 server. By following the path of lights, you can quickly identify the type of
system error that occurred.
Status LEDs are located on the following components:
Operator LED panel
