3.2.3 Add an SSPA Unit to the System
If one of the SSPA units was removed from the system or it down for maintenance,
adding it back to system array may cause an unexpected change to a system state. To
provide uninterruptible system operation, follow the procedure below.
1. Locate the current Master unit and change its N+1 address value to “0”;
2. If the new unit has an unknown N+1 address or has not been configured for
N+1 operation, turn off the Auto Gain option;
3. If the new unit has a known N+1 address in conflict with one of the current
SSPA slave units, resolve it by changing address of the current Slave unit.
4. Add new unit to system. Make sure newly added unit assumed N+1 slave
mode. Make sure current Master unit doesn’t detect any N+1 faults.
5. Change Master unit N+1 address from value “0” to it’s previous value.
