Hallittava kytkin HPE Aruba Networking Aruba 2920 48G POE+

The HP 2920 Switch Series includes five models: HP 2920-24G and 2920-24G-PoE+ with 24 10/100/1000 ports, and HP 2920-48G, 2920-48G-PoE+ and 2920-48G 740W PoE+ with 48 10/100/1000 ports. Each switch provides four dual-personality ports supporting 10/100/1000 or SFP modules, optional support for up to four 10 Gigabit Ethernet uplink ports (SFP+ and/or 10GBASE-T), and an optional two-port stacking module. The series is designed for enterprise edge, remote branch offices and converged networks, offering scalable performance, static and RIP routing, security and management features, free lifetime warranty and software updates.

Advantages

Modular uplink and stacking options allow flexible deployment and easy expansion. Both 24-port and 48-port variants are available with or without PoE+ to meet varied power-over-Ethernet requirements. Enterprise-grade management and security features including SNMPv1/v2/v3, routing and multicast controls support reliable operation in mixed network environments. Energy-efficient design and high-efficiency power supplies reduce power consumption and operating costs.

Key specifications

• Port configurations: 24 x 10/100/1000 (HP 2920-24G / 2920-24G-PoE+) or 48 x 10/100/1000 (HP 2920-48G / 2920-48G-PoE+ / 2920-48G 740W PoE+)
• Dual-personality ports: 4 ports for 10/100/1000 or SFP connectivity
• Optional uplinks: up to 4 × 10 GbE ports (SFP+ and/or 10GBASE-T)
• Stacking: optional two-port stacking module
• Quality of Service: IEEE 802.1p traffic prioritization with 8 priority levels and 8 queues
• Energy efficiency: 80 PLUS Silver certified high-efficiency power supply; Energy-Efficient Ethernet (IEEE 802.3az) support
• Software-defined networking: OpenFlow support for separating data and control planes
• Multicast: IP multicast snooping and data-driven IGMP to prevent multicast flooding
• Resiliency: IEEE 802.1s Multiple Spanning Tree with legacy support for IEEE 802.1d and 802.1w
• Management and security: SNMPv1, v2 and v3 with standard MIB support and SNMPv3 encryption

How to use

Install the chosen HP 2920 model in a standard rack or on a flat surface, connect access devices to the 10/100/1000 ports and use the dual-personality ports for fiber SFP modules where needed. Add optional 10 GbE uplink modules or the two-port stacking module to expand uplink capacity or create a stack of switches. Configure basic network settings, VLANs, QoS policies and routing (static or RIP) through the web interface, CLI or SNMP management tools. For PoE+ models, connect powered devices and monitor power budgets to ensure sufficient PoE delivery.

Recommendations

Choose the PoE+ versions if you need to power IP phones, wireless access points or cameras. Use SFP+ or 10GBASE-T uplinks where higher bandwidth to aggregation or core switches is required. Enable Energy-Efficient Ethernet and use the high-efficiency power supply to reduce operating costs. Apply SNMPv3 and appropriate access controls to secure management traffic.
