my friend has asked me to come and install a new switch he bought.
The top two panels are just the panels that connect to the cabling throughout the floor. The third panel is the switch which I'm about to replace.
My question is, what is the box underneath it? Is has a networked hdd and a wireless phone thing standing on it. Close up:
I would really like to know what it is and what it does before I start changing things. There is no existing network documentation. I'm guessing it might do something with the telephone lines as they are about 10 numbers on the premises.
