How many devices can this switch power via PoE?

The HP ProCurve 3500-24-PoE supports IEEE 802.3af PoE on all 20 Fast Ethernet ports with a total PoE budget of 398W. Each port delivers up to 15.4W, supporting standard PoE devices like IP phones and wireless access points. The number of simultaneously powered devices depends on individual device power requirements.

What is the switching capacity and throughput?

The switch provides 153.6 Gbps crossbar switching fabric with 111.5 million packets per second (Mpps) throughput. This non-blocking architecture ensures simultaneous multi-port traffic without performance degradation, supporting demanding enterprise applications and high-density deployments.

Can this switch be stacked with other units?

Yes, the ProCurve 3500-24-PoE supports stacking up to 16 units together, enabling scalable network expansion. Stacking allows organizations to increase port density and create larger switching fabrics without replacing existing infrastructure.

What management protocols does it support?

The switch supports SNMPv3, SSHv2, SSL, RADIUS/TACACS+ authentication, and IPv6 dual-stack. It includes web-based graphical user interface management, remote intelligent mirroring, IEEE 802.1AB LLDP, and UDLD for comprehensive network visibility and security.

What are the dual-personality ports?

Four ports feature dual-personality design, supporting either 10/100/1000Base-T copper (RJ-45) or 1000Base-X fiber (SFP) connectivity. This flexibility accommodates mixed-media environments and enables future upgrades without hardware replacement.

What is the physical form factor?

The switch is a 1U rack-mountable device with dimensions of 17.44(w) x 16.93(d) x 1.73(h) inches. It includes rack ears for standard 19-inch rack installation and operates with input voltage of 100-127/200-240 VAC at 50/60 Hz.

Does it support Layer 3 routing?

Yes, the ProCurve 3500-24-PoE is a Layer 3 managed switch supporting static IP routing with a routing table size of 10,000 entries. This enables inter-VLAN routing and network segmentation without requiring separate routers.
