A good match for an uneven upgrade
Most small sites do not replace every endpoint at once. Phones and cameras may remain Gigabit devices while a few new access points or workstations need 2.5GbE. The Pro Max 24 PoE is built around that mixed requirement. Cartennas would consider it when the port distribution matches the site closely enough to avoid buying two separate access switches.
The buying argument changes when most connected devices need multigigabit speeds. Moving an uplink to 10G does not change the speed of a Gigabit access port. A plan to grow beyond the eight faster RJ45 ports needs a different switch or a deliberate expansion path.
The port map and power budget must be read together
The USW-Pro-Max-24-PoE has sixteen Gigabit RJ45 ports, eight 2.5GbE RJ45 ports and two 10G SFP+ ports. Sixteen access ports offer PoE++, while eight offer PoE+. Total PoE availability is 400W. The published 112Gbps switching capacity counts both directions; the corresponding non-blocking throughput figure is 56Gbps.
These specifications answer different questions. The switching fabric describes aggregate forwarding capacity. The uplinks describe traffic leaving this switch. The PoE budget describes the shared electrical allocation. A configuration can fit one limit and exceed another. For example, concentrating high-draw devices on capable ports still requires adding their power allocations before the installation is approved.
| Resource | Published limit | Design implication |
|---|---|---|
| 2.5GbE RJ45 access | 8 ports | Prioritize faster APs and endpoints. |
| 10G SFP+ | 2 ports | Allocate upstream and local high-speed links explicitly. |
| PoE availability | 400W total | Budget the combined powered load. |
| IPv4 static routes | 256 | Treat routing scale separately from switch throughput. |
What the hands-on account contributes
A firsthand home-lab account describes straightforward adoption into UniFi and useful per-port controls for VLANs, PoE, aggregation and loop protection. The reviewer chose this model for its combination of ordinary access ports, faster ports and a 10G backbone. Those observations support the management and mixed-device argument.
The same account contains affiliate purchase links and does not provide a controlled enterprise workload test. Cartennas therefore gives more weight to its described setup workflow than to its general enthusiasm or claims about future growth. Ease of adoption is valuable evidence; it does not establish sustained performance under every traffic pattern.
The fan complaint had an important resolution
A community report initially described a used Pro Max 24 PoE running its fans at full speed around a reported 35°C. The original poster later returned that unit as faulty and reported that a new replacement behaved normally. Other owners in the thread described lower fan duty at higher reported device temperatures.
Reading only the initial complaint would produce the wrong recommendation. The discussion points to a problem with that individual unit, while leaving the wider failure rate unknown. It also illustrates why an internal sensor reading should not be confused with room temperature. For an occupied office, the useful decision is whether the actual rack location and operating load meet the site’s acoustic needs.
Routing capability needs a security decision
The switch lists static routing, DHCP functions and local inter-VLAN routing. Those capabilities can move traffic between local networks, but a buyer should map which traffic is supposed to cross the security gateway. Moving a route changes the packet path; it does not automatically preserve the inspection and logging assumptions of the original design.
The same reasoning applies to power redundancy. The supported DC backup input adds a power option. It does not create a second switching fabric or another cable to each endpoint. Cartennas would approve the design after identifying which failure the extra component addresses and what still stops when the switch itself is unavailable.

Choose the Pro Max 24 PoE for a mixed-speed UniFi site whose port count and power allocations fit this exact model. Its strongest benefit is consolidating a practical assortment of devices into familiar management. Choose a different access configuration when most endpoints need faster copper links, when the shared PoE budget is too small, or when the network requires a more extensive routing and resilience design.
