As far as I know, the Netbotz Sensors will be shown N/A while the Netbotz A-Link establishes the communication to the Appliance after the sensors are attached. The Sensors will show the values once the appliance senses the Pods sensors after some time. Do these sensors showing the values after some time? If so, its normal.
If the sensors are still showing N/A on the Advance View, then I request you to do the following:
Please make sure that the Sensor Pod is connected as per the A-Link Communication instructions as per user manual. If possible, Restart the appliance with the sensors and see if the values are shown on the advance view.
Please make sure that the Botzware of the appliance is the latest version.
If the problem remains same, please provide the following details:
How many sensors pods are connected to the appliance?
Is this a new installation or had it been working before?
Are there any sensors connected to the appliance? If so, are they showing the sensor values?

After appliance restart system not found 150 sensor pod, in Advanced view all sensor pods icons go to grey, sensors reading change N/A (only a-link bus power and ethernet link stay normal) and system start send alerts “Sensor unplugged”.
Netbotz 450 -> (alink in) Netbotz 150 (alink out)-> (alink in) AP9520 -> (alink out)terminator. If i disconnect Netbotz 150 all work normal.
This system works 6 months normal to change sensors (It planned to add two Netbotz 150 and change many sensor place). Used only APC sensors.
Now in appliance Netbotz 450 connected 3 AP9335TH, 3 NBES0301, Leak rope all showing values normal. Only after connect 150 in alink all sensors go N/A, it does not matter whether the sensors are connected and 150 power to it, the result is same.
Lates version 4.5.1.

Thanks for your reply.
With a NetBotz 450, you can cascade up to a combined total of two NetBotz Rack Sensor Pod 150s
(NBPD0150) and NetBotz Room Sensor Pod 155s (NBPD0155), plus up to a combined total of eight
Temperature Sensors with Digital Display (AP9520T) and Temperature/Humidity Sensors with Digital
If possible, please verify if the sensor Pod(NBPD0150) is cascaded as shown below.
Please also make sure that the device ID is set correctly for the AP9520TH Display sensors. AP9520TH sensor can not decides its ID/Address on the A-Link bus unless we manually set the switch settings.
I think that AP9520TH dipswitches are probably the cause of the problem. I suggest you to follow the guidelines for dipswitch settings that are located in the manual of AP9520TH and make sure that the following is noted:
Make sure that before connecting the sensors that the dipswitches are set. Connecting sensors with the same address will probably cause the sensor not to show correctly.
Make sure that standard Cat5 cables are being used to connect each sensor.
I hope this helps.

I checked all the connections of the procedure and settings. Effect is still there. Apparently there is a physical deffekt. The warranty period is over, if the point of having to send checks to the nearest APC service?
