Compatible with the the ASUS NUC 15 Pro model NUC15CRH, this 2.5G Ethernet LAN and COM Expansion Module provides an additional 2.5 Gb/s compatible RJ45 LAN and RS-232 serial COM port for your system. This module installs into the chassis expansion slot and links to the motherboard's FFC connector.
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 $35.
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.
