Who do we call to install a new network switch?

We supply and install switches, or install one you already bought. Either is fine.

Three things that decide what you actually need:

• Port count, counted honestly. Every desk, printer, access point, camera, phone, and door controller. Then add a quarter for growth, because you will.
• Power over Ethernet budget. Access points, cameras, and most desk phones draw power from the switch. A switch with enough ports but not enough PoE wattage fails in a way that looks random and is miserable to diagnose.
• Managed or unmanaged. Unmanaged is cheaper and fine for a handful of desks. Once you want your payment traffic, cameras, or guest Wi-Fi separated from everything else, you need managed, and retrofitting that later means replacing the switch.

The unglamorous part matters too. A switch sitting on the floor of a closet with cables hanging off it will cause problems nobody traces back to it for a year. We mount and label as part of the install.
