Troubleshooting
Typical symptoms, causes, and actions
Symptoms or message Cause and/or action
HEAD DID NOT LOAD
The LFP failed to load the operating system
into the head.
Check that all cables are connected, and all
devices have power.
If you have connected more than one head,
connected the MRMC system to another local
network, or moved the controller and head
between networks, check that correct LAN
addresses have been entered in the controller.
See
Working with Local Area Networks on page
56.
Check the order in which the devices are
powering up. If you are using an Ethernet
connection to the head, avoid powering the
head from the power output socket on the
controller in order to avoid powering up the
two devices simultaneously (which can cause
problems on small isolated Ethernet networks).
Use an independent power source for each, and
power up the head first. If you are using a
Serial connection to the head, power up the
controller first.
Data corruption can also cause a failure to load
the head. Use a shorter cable to improve the
communication, and ensure the cable is not
running near any high current devices.
