2.3 What the LEDs mean

Table 4: LED states and what they mean

2.3.1 Exceptions/special conditions for the LEDS

The locate command will make all four LEDs blink on and off synchronously to quickly
identify the module in a larger installation. The condition of the card is not otherwise
affected by the command, only the appearance of the LEDs will change. The LEDs return to
their normal states and functions after the special locate condition has timed out.
