Heartbeat LED, product operating
The following table describes the connectivity operation when the product completes the firmware boot
process and is in the Ready state.
TIP: If the heartbeat LED is illuminated—by an error condition or normal operation—the formatter is
fully seated and the power is on. The pins for the LED circuit in the formatter connector are recessed so
that this LED will not illuminate unless the formatter is fully seated.
