What to do if the Red FAULT LED is blinking slowly on my Cisco Control Unit?
If the Red FAULT LED is blinking slowly on your Cisco Control Unit, it could be due to an improper configuration of the LCM. Verify the LCM configuration. It can also indicate real operating condition problems. Use the PC-based ViewPort software to determine what operating condition alarms exist.
How to troubleshoot 'No Frequency Found State' on Cisco Control Unit?
To troubleshoot a 'No Frequency Found State' on your Cisco Control Unit, connect a laptop computer running the ViewPort software to the local control interface USB port on the LCM. Then, use ViewPort to set the RX FREQUENCY (the downstream frequency) on which the transponder receives commands from the headend. Additionally, use a spectrum analyzer and check for a downstream carrier at the receiver test point.
Why is the green STATUS LED not blinking on my Cisco Control Unit?
If the green STATUS LED is not blinking on your Cisco Control Unit, make sure the LCM is mating correctly with the connectors on the OIB in the node. Remove the LCM from the node and examine the pins of the LCM connectors; if any are bent or broken, replace the LCM. It is also possible that input power is not being supplied to the LCM through the OIB; check and replace the OIB if necessary.
What to do if the Red FAULT LED is on solid on my Cisco Control Unit?
If the Red FAULT LED is on solid on your Cisco Control Unit, use the same procedure as in the case where the Red FAULT LED is flashing fast, but look for the failure of both primary and secondary receivers.
What to do if I can't control Cisco Network Hardware with LCS software?
If you cannot control your Cisco Network Hardware with the LCS software, verify that the USB cable is correctly connected. Also, consult the Cisco GS7000 Super High Output Intelligent Node Software Installation and Configuration Guide to ensure the USB connection mode on your mobile phone is configured correctly.
What to do if there is no RF output on forward RF ports of Cisco GS7000 Network Hardware?
If there is no RF output on one or more forward RF ports of your Cisco Network Hardware, make sure the ports are enabled via LCS. Check the input cabling and RF input levels to ensure they meet expectations. Verify the Fwd RF cable connecting the OIB and Launch amp is properly connected, and confirm the iRPD is functioning correctly.
What to do if there is no RF output on reverse RF ports of Cisco GS7000 Network Hardware?
If there is no RF output on one or more reverse RF ports on your Cisco Network Hardware, first verify the segmentation settings using LCS. Then, check the RF port cabling and ensure the RF input levels are as expected. Finally, confirm that the reverse RF cable between the OIB and launch amplifier is properly connected.
Why is the reverse C/N performance poor on my Cisco Network Hardware?
To address poor reverse C/N performance on your Cisco Network Hardware, first check if the headend performance aligns with the system design target. Next, measure the RF input level to the RPD and verify that it is correct.
What to do if AGC does not lock on Cisco GS7000 Network Hardware?
If the AGC does not lock on your Cisco Network Hardware, verify the RF configuration settings and check the USB cable connection in LCS.
How to troubleshoot a Cisco Network Hardware node that is not powered up?
If your Cisco Network Hardware node isn't powering up, ensure power is connected to the correct inputs and the powering shunts/fuses are properly installed. Verify the power supply is in the correct slot and that AC input power is within the 45 to 90 VAC rms range. Check DC outputs at the power supply test points.
