Troubleshooting
Troubleshooting ControlFiles
All procedures assume that you have found all red fault LEDs and that they
have been corrected before proceeding to the troubleshooting process.
The general procedure is to reduce the ControlFile to a configuration which
you know works. From that point you can selectively add removed
components until the faulty component is isolated.
CAUTION
Use a grounded wrist strap with a built-in one megohm
resistor for your safety and the protection of static sensitive
circuits. The resistor allows static electricity to drain to
ground and still isolates you from direct ground.
Do not touch the gold edge connectors on any board.
Remove all ControlFile circuit boards except the Power Regulator, one
Coordinator Processor, and the Nonvolatile Memory. If the green LED on
the Power Regulator and the Coordinator Processor comes on when
enabled, they should be considered operational. If the Coordinator
Processor does not successfully boot, replace the Nonvolatile Memory,
Coordinator Processor or the Power Regulator. The goal at this point is to
have the ControlFile Coordinator Processor operating.
Next install the the PeerWay Buffers. At this point you should be able to
see the ControlFile Status on the console.
Continue installing the other Power Regulator, Coordinator Processor, and
the C ontroller Processors one at a time until the faulty component is found.
If, at any point, the installation of a circuit card stops the progress of
Booting, that card should be replaced.
CAUTION
When performing this procedure care must be t aken to
disable the Nonvolatile Memory and then the Coordinator
Processors each time a card is removed or inserted (with the
exception of the PeerWay Buffer cards).
Turn off the Nonvolatile Memory card before removing AC
and DC power.
NOTE: Any slot which previously contained a PLC, RBLC, or MUX
Controller must have either a WIPE BUBBLE or KILL CONTROLLER
performed on it prior to loading an image or configuration. Failure to do so
could c ause some strange errors or problems with the controller.
