To identify and resolve issues with a non-functional shelf, please follow the steps below:
Physical Connection & Corrosion Check
Before testing hardware swaps, ensure the physical path is clean and secure:
Reseat Connections: Unplug and firmly reconnect the cable at the back of the shelf and at the IQ box side.
Inspect for Damage: While the cables are unplugged, check the connectors on the shelf and the cable ends for any signs of corrosion, green/white oxidation, or moisture.
Clean if Necessary: If moisture is present, dry the area completely. If corrosion is found, attempt to clean it by gently scraping it off the pins/connectors.
Validate the Fault: If cleaning does not immediately resolve the issue, you must proceed to Step 2 (Initial Cable Test) to confirm if the corrosion has caused permanent damage to the cable/port or if the shelf is the actual culprit.
Initial Cable Test:
Disconnect the cable from the problematic shelf.
Connect the cable from the shelf above or below to the non-working shelf.
Observe the result:
If the issue persists with the new cable: The issue is likely with the shelf itself. Proceed to Step 2.
If the issue is resolved: The problem may be with the original cable or the IQ box connection. Proceed to Step 3.
Inspect the Shelf:
Remove the faulty shelf and flip it over to access the connection board on the back.
Check all internal cable connections to ensure they are secure and undamaged.
Test the IQ Box Connection:
Reconnect all cables to their original positions.
Access the IQ box.
Swap the cable from the non-working shelf with one from a working shelf.
Observe the result:
If the issue moves with the cable: The cable is faulty and should be replaced.
If the issue stays on the same port in the IQ box: The IQ box port is faulty and the IQ box may need to be replaced.
