What PoE capabilities does the HP A5120-48G-PoE EI offer?

It provides 48 RJ-45 10/100/1000 PoE+ ports compliant with IEEE 802.3af/at, delivering up to 30W per port simultaneously with a 370W budget. Optional RPS1600 redundant supply doubles it to 740W, supporting high-density powering of APs, cameras, and VoIP devices without injectors.

Does it support Layer 3 routing?

Yes, as a managed Layer 3 switch, it features static Layer 3 routing and IPv6 forwarding. With 144 Gbps switching capacity and 107.2 Mpps throughput, it handles inter-VLAN traffic efficiently in enterprise access layers.

What stacking technology is used?

Intelligent Resilient Framework (IRF) stacking creates a single logical switch from multiple units, simplifying management and enabling fast failover. Combined with DLDP for cable monitoring, it ensures high availability in stacked deployments.

What expansion options are available?

Two interface slots support modular expansion for 10 Gigabit Ethernet interfaces, plus four dual-personality ports (10/100/1000Base-T or SFP). This allows scalable uplinks to core switches or servers in data centers.

How is the switch managed?

Management includes web browser interface, SNMP, and CLI. Additional features like Ethernet OAM for link fault detection, dual flash images for OS backup, and multiple configuration files enhance operational reliability and recovery.

What is the form factor and power supply?

1U rack-mountable (1.72 inches height) with a single non-modular internal AC power supply. Idle power is around 78W, max 550W with PoE, and frequency support of 50/60 Hz suits standard enterprise rack environments.
