IP telephony deployments leveraging the 180W PoE+ budget to power 24 IP phones simultaneously with QoS prioritization ensuring voice call quality and reliability across the network.
WiFi infrastructure supporting multiple wireless access points powered via PoE+ with 4 SFP fiber uplinks providing high-speed backbone connectivity to core network switches and servers.
Security camera deployments with integrated PoE+ power delivery to 24 IP cameras simultaneously, supporting video streaming and storage with VLAN isolation for security network segmentation.
Point-of-sale systems, guest WiFi networks, and IoT devices in retail stores and hospitality venues requiring managed switching with PoE+ power and Layer 3 routing capabilities.
The HPE JG925A provides 180W total PoE+ power budget across all 24 ports, compliant with IEEE 802.3at standard. This enables simultaneous powering of approximately 24 IP phones (7.5W each), 12-15 wireless access points (12-15W each), or 18-24 IP surveillance cameras (8-10W each) without requiring separate power supplies or PoE injectors.
The switch provides 56 Gbps total switching capacity with 41.7 million packets per second forwarding rate, ensuring non-blocking wire-speed performance across all ports simultaneously. Latency is less than 5 microseconds at 1000Mbps, making it suitable for latency-sensitive applications including VoIP and video streaming in enterprise networks.
Yes, the JG925A includes Layer 3 static routing capabilities supporting OSPF, RIP, and BGP protocols. This enables inter-VLAN routing and network segmentation without requiring external routers, reducing infrastructure costs and complexity in branch office and campus deployments.
The switch includes enterprise-grade security features including 802.1X network login authentication, Access Control Lists (ACLs) for traffic filtering, port security to prevent unauthorized access, and RADIUS authentication integration. SSL and MD5 encryption protect management sessions, while VLAN support enables network segmentation for security policy enforcement.
Management options include web-based GUI, command-line interface (CLI), SNMP v1/v2c/v3, RMON 2, Telnet, HTTP, HTTPS, and TFTP. This enables integration with enterprise monitoring systems, centralized configuration, and remote administration via secure encrypted channels (SSH, HTTPS).
The switch measures 44 x 23.8 x 4.4 cm (1U height) and weighs 3.4 kg, fitting standard 19-inch equipment racks. It requires a single AC power supply supporting 50/60 Hz, 100-240V AC input, with operating temperature range of 0°C to 40°C for reliable performance in various deployment environments.
Yes, the JG925A is ideal for both applications.
