HAPTER 11: FAULT MANAGEMENT
Configuring Fan Unit Assertion Levels
The ADC-provided fan unit utilizes an active low signal to inform the
management module of system faults, so ensure that the assertion level for
fan temperature and fan rotation faults is set to active low. To set the
assertion level logic used by the fan tray unit to report temperature and
rotation faults, follow this procedure:
1. In the Hardware Alarm Configuration window, click the Fan Supply
Assertion Levels tab.
2. Select the proper fault level for the Fan Temperature and Fan Rotation.
The signal that the device sends can use one of these assertion levels:
Active High Signal indicates the assertion state as a logic ONE state.
Active Low Signal indicates the assertion state as a logic ZERO
state.
3. Click Apply to commit the changes or click Reset to exit without saving.
4. Click Refresh to update the information.
