Product Features
Technical Overview
Engineered for reliability and efficiency, this switch supports a comprehensive set of networking standards including IEEE 802.3af/at for PoE, IEEE 802.1Q for VLANs, and IEEE 802.1x for network access control. The 370W PoE budget intelligently allocates power across all 24 ports, enabling simultaneous operation of multiple PoE+ devices without overloading the system.
The built-in power supply accepts 120-230V AC input, with a maximum power consumption of 490W under full load. Auto Denial of Service (DoS) prevention and energy-efficient Ethernet (IEEE 802.3az) features enhance security and reduce operational costs in always-on environments.
This section brings together practical product details such as Features, Total Number of Network Ports, Network (RJ-45), Uplink Port, so buyers can judge configuration, deployment fit, and day-to-day suitability with less guesswork.
A strong technical summary explains how the product's interfaces, hardware profile, and operating characteristics work together in real deployment.

Deployment / Use Cases
This switch excels in small to medium business environments where reliable connectivity and power delivery are critical. Its 24 PoE+ ports make it perfect for office floors with concentrated IP telephony and wireless deployments, eliminating the need for separate power injectors and reducing cable clutter.
In retail or education settings, the switch can power surveillance cameras, digital signage, and access points while providing high-speed backhaul through fiber uplinks. The lifetime warranty and RoHS compliance ensure long-term reliability and environmental responsibility across these deployments.
Unified Communications Ready
Power and connect IP phones, video conferencing systems, and collaboration devices with consistent quality of service.
Wireless Infrastructure Backbone
Deploy multiple Wi-Fi 6/6E access points with full PoE+ power while maintaining 10G uplinks to the core network.
Physical Profile
The compact 1U form factor (1.73" height) maximizes rack space efficiency in standard 19" cabinets. The steel chassis provides durability while the fanless design ensures silent operation in office environments. Front-to-back airflow and multiple ventilation points maintain optimal operating temperatures even under full PoE load.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 1.73" (43.90 mm), 17.42" (442.50 mm), 10.42" (264.70 mm), 8.22 lb (3730 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.

User Manual
FAQ
What is the total PoE budget and how many devices can it power?
The switch provides a 370W PoE budget across all 24 ports. This can power approximately 24 standard PoE devices (up to 15.4W each) or a mix of PoE+ devices (up to 30W each), such as 12-15 modern wireless access points or IP cameras with heaters/blowers.
Can I use fiber connections with this switch?
Yes, the four SFP+ slots support both fiber and copper transceivers. You can use 1G or 10G SFP/SFP+ modules for fiber connections to other switches, routers, or servers, enabling longer distance links up to 80km depending on the optic chosen.
What management features does the smart managed interface include?
Management features include VLAN support (802.1Q), Quality of Service (802.1p), port mirroring for troubleshooting, LLDP for device discovery, storm control, and web-based configuration. It also supports the Aruba Instant On mobile app and cloud management for remote monitoring.
Is this switch suitable for rack mounting in a standard server cabinet?
Yes, it's designed for standard 19" racks with 1U height (1.73"). The switch includes rack ears and supports both front and rear mounting. The depth of 10.42" fits most shallow and deep cabinets, and weight of 8.22lb makes it easy to install without additional support.
