The Axis Communications D8248 is a robust 48-port Gigabit PoE++ compliant managed network switch, designed for demanding network environments. It features 48 RJ45 Gigabit Ethernet PoE ports, supporting 802.3af, alongside 4 SFP+ 10 GbE uplinks, all within a rack-mountable steel chassis. With a substantial 740W PoE power budget, a 176 Gb/s switching bandwidth, and Layer 2/3 services, this switch is ideal for powering and connecting a wide array of network devices, including IP cameras and other PoE-enabled equipment, across large-scale installations.
For home use, a simple unmanaged Gigabit switch is all you need to expand your router's ports. Buy a managed switch or a switch with PoE only if you are running security cameras, access points, or complex VLAN setups. Available from $2,009.
Basic unmanaged network switches use negligible power and have zero maintenance costs. PoE (Power over Ethernet) and large managed switches use more electricity but are still relatively cheap to run.
Common Failure Modes
Switches are solid-state devices with high reliability. When they fail, it is usually due to lightning strikes/power surges blowing individual ports or the internal power supply dying.

Network switches are extremely reliable solid-state devices. They are usually replaced because networking speed standards outgrow them, rather than due to hardware failure.
