⚡ Advanced PoE+ Technology
The PoE+ (Power over Ethernet Plus) standard, compliant with IEEE 802.3af and 802.3at standards, allows for the simultaneous transmission of data and power over a single standard RJ45 Ethernet cable. This revolutionary technology significantly simplifies the deployment of your network equipment by eliminating the need for individual power outlets and bulky power adapters.
Each PoE+ port on this switch can deliver up to 30 watts of power, enough to power even the most demanding devices such as tri-band Wi-Fi 6 access points, high-resolution 4K PTZ cameras, and IP phones with color touchscreens and HD video. The switch's total PoE budget allows for the simultaneous powering of numerous devices with intelligent power management.
Automatic PoE detection (Auto-sensing) ensures complete compatibility without risk of damage to non-PoE devices accidentally connected. The switch automatically detects if the connected equipment requires PoE power and provides the appropriate power only when needed. This built-in intelligence ensures the safety and protection of your existing hardware investments.
🔐 Advanced Management Features

The multi-method management interface (command-line CLI, intuitive graphical web interface, SNMP, secure SSH) allows for flexible administration tailored to your IT team's preferences.
Virtual LANs (VLANs) allow you to logically segment your physical network into multiple isolated virtual networks to separate traffic by department, function, or security level. Up to 4,096 configurable VLANs offer exceptional granularity for complex infrastructures. QinQ support enables VLAN encapsulation for carrier and managed service provider architectures.
Quality of Service (QoS) features with 8 queues per port ensure intelligent prioritization of critical network traffic such as VoIP, video conferencing, and real-time business applications. STP/RSTP/MSTP redundancy protocols provide high availability and protection against network loops. iStack technology allows you to virtualize up to 9 physical switches into a single logical switch for simplified management and seamless scalability.
