Power over Ethernet allows one cable to carry data and power to access points, cameras, phones, bridges, and access devices. Correct switch sizing requires more than counting ports.
Understanding PoE budgets
Each powered device draws from the switch's total PoE budget. A switch can have many PoE-capable ports and still lack enough total power for all connected devices.
We review device requirements, startup draw, future expansion, and whether higher-power standards are needed.
Managed switching
Managed switches provide visibility into links, VLANs, PoE status, traffic, and connected devices. This is valuable for troubleshooting and network separation.
UniFi switching integrates with the gateway and access points for centralized management.
Uplinks and multi-gig needs
Access points, recorders, servers, and downstream switches may require faster uplinks. Multi-gig ports or fiber uplinks are considered where they provide real value.
Installing high-speed access points on a limited uplink can create an unnecessary bottleneck.
UPS and centralized power
PoE devices can remain online during short outages when the switch and upstream network equipment are protected by a UPS.
This is especially useful for cameras, phones, access control, and remote-building links.
Switch placement
Central racks, remote cabinets, barns, shops, and outdoor enclosures may each need switching. Environmental conditions, access, power, and fiber or bridge uplinks influence placement.
Remote switches are labeled and documented as part of the overall network.

Frequently asked questions
What does PoE power?
Common devices include access points, security cameras, VoIP phones, bridges, readers, and intercoms.
Can any PoE switch power any device?
No. Devices and switches must support compatible PoE standards and the switch must provide enough per-port and total power.
Can PoE run over existing Ethernet?
It can run over suitable, correctly terminated cabling. Existing cable should be inspected or tested.
Can a UPS keep cameras online?
Yes, when the gateway, switch, recorder, and internet equipment are included in the backup plan.
