PER (Packet Error Rate) in Harmonic XOS indicates the rate of errors in received transport stream packets. If it is bouncing into the red on one of the tuners, follow these steps to troubleshoot:
1. Launch the Platform Configuration app and go to the RF / Tuner tab. 2. Check the LO (Local Oscillator) frequency and confirm it matches the characteristics of the antenna (LNB). 3. Verify tuner settings. 4. Monitor the statistics and counter values for a few minutes to observe performance. 5. Check antenna connectivity. 6. If available, use another XOS to compare behavior on the same feed.
These steps help identify issues with signal quality or incorrect configuration.

How to configure the time synchronization If required, the XOS can be connected to an NTP server for time synchronization. This type of configuration requires Internet connectivity for operation. Launch Platform Configuration. Select the Time tab.
To configure static IP addresses for iLO and Management ports through the local console, do the following: Connect the monitor, keyboard, and mouse to the XOS. Turn on the platform. During startup, press F9 for the System Utilities option.
Select F12: Save and Exit to confirm the changes and to restart the platform. How to configure SNMP trap destination The XOS offers a Rest API in the UI so you can configure the list of SNMP recipients for the trap destination. ...

Questions and answers
What is per and how do I fix it since it is bouncing into the red on one of my tuners?
PER (Packet Error Rate) in Harmonic XOS indicates the rate of errors in received transport stream packets. If it is bouncing into the red on one of the tuners, follow these steps to troubleshoot:
1. Launch the Platform Configuration app and go to the RF / Tuner tab.
2. Check the LO (Local Oscillator) frequency and confirm it matches the characteristics of the antenna (LNB).
3. Verify tuner settings.
4. Monitor the statistics and counter values for a few minutes to observe performance.
5. Check antenna connectivity.
6. If available, use another XOS to compare behavior on the same feed.
These steps help identify issues with signal quality or incorrect configuration.
