请教，每个ATA/serial number 有一个Configuration page， 还是每个IP地址有一个？谢谢！

Briefly, my question is how to test a new SPA1001 without messing up the configuration on the working one? Thank you very much!

这个问题看起来有点奇怪！原因是又买了一个

SPA1001作为Backup. 想检测一下这个ATA, 又不想把原来ATA的设置弄乱，就有了以下的问题：

每个ATA/serial number 有一个Configuration page， 还是每个IP地址有一个Configuration page？I guess it goes with serial number and IP address.

同一个IP地址可以同时连两个ATA吗？If configuration goes with serial number and IP, the answer is No. Only one at a time, so new SPA1001 configuration won’t mess up the previous one. Am I right?

谢谢啦！
