10.4.8. Replacement of I/O Card
Important:
The controller should be powered down before disconnecting any RJ45 connector.
I/O cards are situated on the back panel of the controller cabinet. Disconnect the cables which are held
in place with two screws each, then the serial cables and the six mounting screws. Remove the card
and replace with the new one. Reverse the procedure to connect the new card.
10.4.9. Replacement of CIC Card
Important:
The controller should be powered down before disconnecting any RJ45 connector.
Pull the spring clip under the CIC card and pull the card part way towards you using the front handle.
Tilt the top of the card away from the side of the cabinet, lining up a notch on the card with the
projection on the card holder, then pull the card right out.
Replace with the new CIC card by reversing the above procedure.
Important:
Remember to set the CIC card address to be the same as was set on the faulty card.
Important:
CIC in position 3 is reverse orientation; the spring clip is on top.
If the backplane is also removed, ensure all street cables are reconnected in the same positions.
Ensure that the SPB and SIO cables are connected in the same orientation on the replacement
backplane card.
