Q: How can I check connectivity between RU and BBU?
A:
You can check the state of the monitor, specifically the promise named "RU*cpri-lock". You are supposed to see at least "HW lock", meaning the hardware is connected.
Please find more information:
If you are close to the RU, you can also check the LED indicator on the device:
- PWR should be steady on
- RUN should be slow blinking
- OP1 should be steady on
Please check section Table 2-2 ORRU Indicators
