24-Port PoE Switch Buying Guide: Six Models Worth a Look

A small office adds eight ceiling access points, a dozen IP cameras and a handful of desk phones, and suddenly the closet switch has run out of ports. That is the moment a 24-port PoE switch earns its place: one device that supplies both data and electrical power over a single Ethernet cable, so cameras and access points can sit wherever the cable can reach, with no wall outlets needed nearby.

The right model depends less on the port count than on the power budget, the management style and the uplinks. The six switches below come from established networking brands and cover unmanaged, smart and fully managed approaches. Features such as total wattage and port speeds should always be confirmed on the manufacturer’s data sheet for the exact model code.

Quick Picks

How to Choose

Add up the power budget before counting ports

A switch advertises a total PoE budget in watts, and it is shared across every port. Standard PoE (802.3af) delivers up to 15.4 watts per port, PoE+ (802.3at) up to 30 watts, and PoE++ (802.3bt) up to 60 watts or more. Add the draw of every camera and access point, then leave at least 20 percent headroom. A switch with a 24-port label but a modest total budget cannot run 24 high-draw devices at once.

Decide between unmanaged, smart and fully managed

Unmanaged switches need no setup and suit simple networks. Smart or web-managed models add VLANs, port mirroring and basic QoS through a browser. Fully managed switches add command-line control, link aggregation, spanning tree and detailed monitoring. A good rule of thumb: if you have more than one subnet, separate camera traffic, or need remote diagnostics, buy managed.

Look for uplink ports that match your backbone

Many 24-port switches add two to four extra uplink ports, often SFP or SFP+ for fiber. If the switch will feed other switches or a server, look for at least one 10-gigabit uplink or a pair of gigabit SFP ports. A gigabit-only uplink can become the choke point when every camera streams at once.

Check mounting, noise and thermals

A 24-port switch usually fits a standard 19-inch rack with 1U height, but some models are desktop-style. If the device sits in an open office, look for fanless designs or confirm fan noise specs. Devices that push the full PoE budget run warm, so allow airflow around the vents.

A worked example makes the power math concrete. Suppose a site has ten ceiling access points drawing about 13 watts each, eight outdoor cameras drawing about 12 watts each, and four desk phones drawing about 7 watts each. That adds up to roughly 254 watts, so a switch with a total budget of 370 watts leaves about 45 percent headroom, while a 250 watt budget would be at the limit before any new device is added. Always size from the devices you actually plan to connect, not from the port count.

Redundancy deserves a thought as well. A single switch is a single point of failure for every camera and access point it powers, so critical sites often add a second switch or a small battery backup. Look at the switch’s rated operating temperature and whether it supports power-supply redundancy, and place the unit in a ventilated rack rather than a sealed wall box.

Our Picks Reviewed

NETGEAR GS524PP

The GS524PP is a NETGEAR switch whose code indicates 24 ports and a PoE+ class. NETGEAR’s naming makes it easy to place in the unmanaged family, which appeals to installers who want zero configuration.

• Pro: unmanaged-class switches work the moment they are plugged in, which suits small shops and temporary sites.
• Pro: 24 ports cover a typical cluster of cameras, phones and access points on one device.
• Con: unmanaged designs do not offer VLANs or detailed monitoring, so growth into segmented networks needs a replacement.

Skip it if you need to isolate camera traffic or monitor port-level power draw remotely.

Ubiquiti UniFi Switch 24 PoE

The name states plainly that it has 24 ports and PoE, and it belongs to the UniFi lineup, which centers on a single controller interface. It is an obvious fit where UniFi access points and cameras already exist.

• Pro: one management dashboard for switches, access points and gateways reduces day-to-day admin.
• Pro: 24 PoE ports let you power a full floor of UniFi devices from one closet.
• Con: the experience depends on the controller, so using it as a standalone switch wastes most of its value.

Skip it if your network is built on another vendor’s ecosystem and you prefer a standard web or command-line interface.

Ubiquiti UniFi Switch Pro 24 PoE

The Pro naming places this model above the standard UniFi 24 PoE switch in the same family, with 24 ports and PoE written right in the name. It is aimed at larger or more demanding UniFi networks.

• Pro: the Pro tier usually brings extra capabilities over the base model, which gives room for growth.
• Pro: it keeps the single-controller workflow, so adding it to an existing site is straightforward.
• Con: a higher tier within a family generally costs more than the base version, which may be unnecessary for small sites.

Skip it if the basic UniFi 24-port model already covers your device count and uplink needs.

TP-Link TL-SG3428MP

TP-Link’s SG3 series is its managed switch line, and the 28 in the code suggests 24 ports plus four extra. The MP suffix is TP-Link’s marker for a PoE-capable variant.

• Pro: a managed class unlocks VLANs, which helps separate cameras and phones from office computers.
• Pro: the extra ports beyond 24 can serve as uplinks to other switches.
• Con: managed switches take time to configure, so a beginner may find the interface heavier than needed.

Skip it if you only need a simple plug-in setup with no VLAN planning.

Cisco CBS350-24P-4G

The Cisco Business 350 series is a managed line, and the code says 24 PoE ports (24P) with four gigabit uplinks (4G). It suits offices that want a recognizable enterprise brand and a documented management interface.

• Pro: the code itself tells you the layout, 24 powered ports plus four uplinks.
• Pro: managed features support segmented networks and formal IT policies.
• Con: enterprise brands often carry a premium and a steeper learning curve than consumer-oriented alternatives.

Skip it if you are setting up a home lab and do not need a business-grade management stack.

Zyxel GS1900-24HP

Zyxel’s GS1900 series is a smart-managed line, and the code shows 24 ports with an HP suffix for the PoE variant. It sits between unmanaged and fully managed in terms of control.

• Pro: smart-managed switches provide VLANs and basic QoS through a web interface, without a command line.
• Pro: 24 ports fit a mid-sized small business closet.
• Con: smart-managed tiers may lack advanced routing or stacking found on fully managed models.

Skip it if you plan to build layered networks that need advanced routing features.

Which One Fits

• Shops and clinics wanting zero setup: NETGEAR GS524PP.
• UniFi-based offices: Ubiquiti UniFi Switch 24 PoE, or the Pro model for larger sites.
• IT staff who want VLANs and extra uplinks: TP-Link TL-SG3428MP.
• Business networks with Cisco policies: Cisco CBS350-24P-4G.
• Smart-managed on a tight setup: Zyxel GS1900-24HP.

A simple way to decide is to start from the management style and work outward. If nobody on site will ever log in to the switch, the unmanaged NETGEAR route avoids a configuration burden altogether. If the network already uses a controller from one vendor, staying inside that ecosystem usually saves hours of setup. If you need to isolate traffic or integrate with a larger corporate network, the managed Cisco and TP-Link options are the natural fit, with Zyxel covering the middle ground for sites that want VLANs without a command line.

Warranty and firmware support matter over a switch’s multi-year life. Check how long the manufacturer publishes security updates for the model family, and whether replacement is handled by advance exchange. For a closet that runs cameras around the clock, a longer warranty period is worth real consideration.

Common Mistakes

1. Reading 24 ports as 24 powered devices without checking the total PoE budget.
2. Mixing PoE standards and assuming every camera works on every port.
3. Skipping VLANs on a network where cameras and office PCs share one flat segment.
4. Choosing a gigabit uplink for a switch that feeds a busy server room.
5. Mounting in a closed cabinet with no airflow, causing thermal throttling.

Documentation pays off here. Label each cable at both ends, record which port feeds which camera or access point, and keep a copy of the switch configuration somewhere safe. When a device drops offline at night, that record turns a long search into a thirty-second check.

FAQ

Do all 24 ports provide PoE?

Not always. Some models power only part of the ports, so confirm that every port is PoE-capable and read the combined wattage.

Is a managed switch worth it?

If you run cameras, voice and office traffic together, managed is worth it for VLAN separation and monitoring. Small flat networks can stay unmanaged.

Can I use a switch with 48 ports instead?

Yes, but pay for ports you may never use. Count current devices, add 30 percent for growth, and choose accordingly.

What cabling should I use?

Look for solid-copper Cat5e or Cat6 rated for PoE; copper-clad aluminum cabling can overheat under load.

Does a PoE switch help my display setup?

Not directly, but a well-designed desk may also benefit from a larger screen; see the 1440p gaming monitor guide if you are upgrading gear at the same time.
