Possible Causes | Steps of Solution |
1. SMPS is Faulty | 1. If power is received at the cabinet(s) where Main Power is connected,
check if the SMPS through which power is provided to Receiver Card is giving an
output of 5V-DC. If NO, Change the same. |
2. 5V Connector is Faulty | 1. If the SMPS mentioned in Scenario-1 is working, check if 5V is
obtained at the Receiver Card. If not, change the 5V Connector (Cable connected
for power from SMPS to Receiver Card). |
3. Loop Data Cable is loose OR Faulty | 1. Check the Data Loop Cable (which is connected from cabinet to
cabinet) by bypassing it to the next Cabinet/Receiver Card. If it doesn't work,
replace the same. |
4. Receiver Card is Faulty (If there is only 1 Main Data Cable) | 1. If all power & data concerns are working fine, check the Receiver
Card (in which Main Data is connected) by bypassing it to the 2nd
Cabinet/Receiver Card. If it works, replace the 1st Receiver Card and
re-program the same. (Kindly connect to our Helpdesk for assistance of programming). |
