Yuhang and Michael

During the recover of filter cavity facilities, we found a router is broken. This router is used for intra-arm second target remote control and pico-motor control. It is essential to repair it.

Accidently, we found a new router around. After just replacing the old router with a relatively new one, the router works again. (new and old routers are shown in the attached figure 1, we can see the old one shows very yellow)

The old router is labelled with a piece of pink tape with broken written on top.
