Control and Indicators
Internal Diagnostic Panel (Optional Accessory)
The Internal Diagnostic Panel LEDs are located inside the server under the top cover (rack) or left cover
(pedestal). The LEDs have the following behaviors:
•
OFF: The component is OK or there is no component.
•
ON (color amber): The component needs attention (failure, pre-failure, early-warning condition,
configuration error, etc.). Whenever an LED turns on, the HP Server tc4100 notifies you by turning the
System LED (located in the front panel) to amber or red.
•
LEDs are powered as long as AC is present (Vstby). They do NOT turn off when the server is powered off.
•
LEDs reflecting actual sensors should turn OFF when the sensors return to normal. Note that a system reset
always returns sensors to normal. If the error condition is still present when the system comes back up, the
sensor should go back to the error state within one minute.
Some LEDs are triggered by SEL events (for example, DIMM configuration error) and will only be cleared by
a system reset. After resetting, the LED should be cleared until a new SEL event is logged. These LEDs should
stay lit even if the server is turned off.
