10.4.10. Replacement of Intelligent Detector Backplane Card
Important:
The controller should be powered down before disconnecting any RJ45 connector.
The Detector Backplane card(s) is/are situated at the rear of the rack.
Generally speaking, only the Intelligent Detector Backplane card will need replacing, although the
replacement kit includes a passive Detector Backplane. They are supplied together to protect delicate
components and connections.
Remove the three nuts holding the card in place and pull away from the passive backplane. Replace
with the new card and tighten the nuts.
Reassemble and return the kit including the defective card to;
Yunex Traffic

10.4.11. Replacement of the Manual Panel Card
First unplug the cable connecting the panel to the CPU Card.
The panel is retained by a number of screws to the main cabinet assembly. (Mounting methods may
vary in different cabinets).
After removal of these screws the panel may remain stuck in place by the gasket. Ease the panel away
from the housing, gradually working from one corner taking care not to scratch or otherwise damage it.
The replacement panel should be mounted with a new gasket to prevent water ingress. After fitting,
reconnect the cable to the CPU Card.
An Internal Manual panel (where fitted) can be removed directly by removal of the screws holding it to
the 19 inch panel; it may be easier to remove the 19" panel from the rack first. As there is no gasket on
an internal Manual Panel, no sealing is required on refitting.
