48-port Layer 3 switch for managed networks

The USW-Pro-Max-48 is a rackmount managed switch built for networks that need Layer 3 routing between local VLANs. It provides 48 RJ45 downlinks and four 10G SFP+ uplinks in a single 1U appliance. Administrators configure it through UniFi Network 8.0.24 or later.

Etherlighting ports and DC backup input

Each RJ45 port uses Etherlighting illumination to show link speed, status and native VLAN at a glance, especially when paired with Etherlighting patch cables. A USP-RPS DC input sits alongside the universal AC supply so the switch can stay online during a power-source failure. No PoE circuitry is present, keeping the maximum draw to 100 W.

112 Gbps non-blocking throughput with 2.5 GbE access

Sixteen ports negotiate at 2.5 GbE while thirty-two operate at 1 GbE, giving mixed-speed clients headroom without oversubscribing the 112 Gbps fabric. The four 10G SFP+ uplinks handle aggregation to core switches or servers. Networks that require PoE for phones, cameras or access points will need a different model.

Questions about this item

What is the maximum power the USW-Pro-Max-48 will draw when fully loaded?

The switch has a maximum power consumption of 100 W under full load.

Which throughput limit is reached first when all 48 ports run at wire speed?

Total non-blocking throughput is 112 Gbps while switching capacity is 224 Gbps, so the 112 Gbps aggregate limit appears first.

How much heat must the rack dissipate when the switch runs continuously at full load?

At the 100 W maximum power rating, the unit converts that electrical draw directly into heat, requiring the rack airflow to handle 100 W of thermal load.
