24-port Gigabit switch with PoE++

The GS728TXUPv3 is a rackmount smart switch offering 24 RJ45 ports at 10/100/1000Mbps and four dedicated SFP uplinks. Sixteen ports deliver PoE+ and eight ports deliver PoE++, giving a total PoE budget of 420W for access points, cameras and VoIP phones. Layer 3 static routing supports 32 IPv4 and 32 IPv6 routes for local inter-VLAN traffic. Cloud and remote management are available through the Insight mobile app and Cloud Portal.

Quiet operation and power profile

Acoustic output ranges from 26.80dBA to 37.3dBA at 25°C ambient, allowing deployment in noise-sensitive rack environments. Maximum power draw reaches 502W when the PoE budget is fully utilised and drops to 27W without PoE load. Energy Efficient Ethernet (IEEE 802.3az) reduces consumption on idle links. The 1U chassis measures 440 x 257 x 43 mm for standard rack mounting.

Insight cloud platform and security tools

The bundled Insight ecosystem provides zero-touch provisioning, multi-site visibility and concurrent multi-port configuration from a single pane of glass. Security features include IEEE 802.1x with RADIUS and TACACS+ admin access, MAC lockdown, DHCP snooping and ACLs at L2/L3/L4. IPv6 management, SNMP v3 and configurable management VLAN complete the administrative toolkit.

Questions about this item

How do I install the GS728TXUPv3 in a rack and what clearance step is often missed?

Mount the 440 mm wide chassis using the supplied brackets; the step often missed is leaving at least 43 mm depth clearance behind the switch for cable bend radius and airflow.

What maintenance or replacement will the GS728TXUPv3 need over time?

The internal fan is the only moving part; clean its intake vents periodically and expect to replace the fan assembly if bearing noise appears after years of continuous operation.

What limit appears first on the GS728TXUPv3 under sustained full PoE load?

The 420 W PoE power budget is the first hard limit; with 16 PoE+ and 8 PoE++ ports active the switch will enforce per-port priority before reaching the 502 W total consumption ceiling.
