4.2. Module Status LEDs

There are six module status indicators on the module front panel: three Healthy, one Active, one

Standby, and one Educated. The Healthy indicators are controlled directly by each module slice. The

Active, Standby, and Educated indicators are controlled by the FPU. The FPU receives data from

each of the module slices. The FPU performs a 2-oo-3 vote on each data bit from the slices and sets

the indicators accordingly.

The module status indicator modes and their meanings are described as follows:

Amber Slice is in the start-up state (momentary after

installation or power-up)
