Check power supply and power supply
voltages. Check cabling and that the
appropriate power shunts are installed in the
launch amplifier.

If Heartbeat LED and Communication LED
blink on power up and then stay off, problem
is with boot. Can be a device failure or
software is not loaded. Try cycling power.

OS is ok but node control software is not
running or is stuck. If this condition persists
for more than a minute or two after power
up, check all the cables connecting the lid
and launch amplifier. Try cycling power.

This condition should not be possible unless
Heartbeat LED is damaged.
