Hi,
RPB: Redundant Power Supply Failure
If you are using redundant power supply, check your redundant power supply.
If you are using single power supply,it is recommended to connect the input terminals SA/SB on the CPU to +24 V.

Under the Unit Status tab you can see the current and latched status of the unit.
For this unit the following statuses can be detected:
1.Battery Low (16#80020000) - Indicates that the backup battery on the CPU is low, or missing.
2.RPA (16#40020000) - Redundant power A failure.
3.RPB (16#20020000) - Redundant power B failure.
Hello,
ModuleBus Clustermodem module base TU807/TU840/TU841/TU841/TU848/TU849 containing TB840 module will have the facility to monitor power supply status through SA and SB connections.
This is similar to Controller base TP830 power supply monitoring connections, SA and SB.
If any base of TB840 module (TU807/TU840/TU841/TU841/TU848/TU849 ) missing the above connections (SA or SB), this system alarm will be generated.
