I've recently found myself taking over the IT responsibilities for my company (a medium sized machine shop). I've got my A+ and am actively working on my Network+, but I'll be the first to admit I still have a lot to learn.
While taking inventory of the server room, I realized that I did not completely understand how a small business such as mine connects to the WAN/internet. Attached to the server rack I see:
- A few patch panels
- A Mitel VoIP Phone Controller
- Two Netgear Switches
- A Cisco Security Appliance
- A UPS System
What I do not see is a router or a modem, at least not in the way I'm used to seeing them. Additionally there are no cables coming from the wall other than power and Ethernet/phone.
Is one of these appliances performing the function of a router/modem? Or is it possible there's one in the building in an area I haven't located yet? Or is this a service the ISP we are connected to would configure?
I just wanted to ask for the sake of my own learning, any clarifying thoughts would be appreciated.
