1.After successfully booting, the boot LED pulses in a “heartbeat” pattern to indicate that the ISM is operating. As crypto traffic increases, the nominal level of this LED increases in proportion to the traffic level.
The following conditions must all be met before the enabled LED goes on:
•The ISM is correctly connected to the backplane and receiving power.
•The system bus recognizes the ISM.
If either of these conditions is not met, or if the router initialization fails for other reasons, the enabled LED does not go on.
