DS1-28/DS3-EC1-3 and DS1-84/DS3-EC1-3 Card-Level Indicators

Card-Level Indicators

Description

Red FAIL LED

Indicates that the card processor is not ready. This LED is on during reset.
The FAIL LED flashes during the boot process. Replace the card if the red
FAIL LED persists in flashing.

ACT/STBY LED
