Model: EX78924E-0VB
from $2,101.45
The EtherWAN EX78900E Series is a hardened, managed Ethernet switch designed for robust network connectivity in demanding environments. It features 8 Gigabit PoE+ ports, each delivering up to 30W (802.3at) with a total power budget of 240W, alongside 4 dual-rate Gigabit SFP ports for flexible fiber optic connections. Built with an aluminum housing, this switch offers reliable operation in extreme temperatures from -40 to 167°F, making it ideal for industrial, outdoor, or other challenging applications requiring resilient network infrastructure and power delivery.
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 $2,101.45.
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.
