Cisco Business 350 CBS350-48T-4X Rackmount Gigabit Managed Stack Switch, 48x RJ-45, 4x SFP+

The CBS350-48T-4X is basically an Ethernet switch made by Cisco Systems, a well-known tech company. It falls under the Catalyst 350 Series, a range of switches specifically created for small and medium-sized businesses.

It features Energy Efficient Ethernet (EEE). It's a design standard that helps reduce power consumption when your network isn't very active.

Sometimes, there's just not much traffic going on. During those times when there's not a lot happening on your network, the switch will automatically kick into EEE mode. It'll lower its power usage, kind of like turning down the brightness on your phone when you're not using it. It's a clever way to save energy and be more environmentally friendly. So, when there's a lull in network activity, your switch won't be a power-hungry monster. Instead, it'll be more like a power-saving superhero! And don't worry, as soon as your network starts buzzing with activity again, the switch will ramp back up to its regular power mode.
