What is the switching performance?

Features 128 Gbps switching capacity, up to 95 Mpps throughput (64-byte packets), and latency under 1.3 µs. Wire-speed Gigabit across all ports with 16,000 MAC address table entries and 2,000 routing table size for Layer 2+ operations.

Does it support PoE+ and what power does it deliver?

Yes, IEEE 802.3af/at compliant PoE+ provides up to 30W per port with dynamic allocation via LLDP-MED. Ideal for high-power devices like pan-tilt-zoom cameras and full-color IP phones, with power adjustable from 0.1W.

What management features are available?

Layer 2+ managed switch with static IPv4 routing, RIP v1/v2, ACLs, sFlow, rate limiting. Supports CLI, HP ProCurve Manager Plus, SNMP, RMON for monitoring. Enterprise-class security and free software updates included.

What is the form factor and power requirements?

1U rack-mountable design. Operates on 100-127/200-240 VAC at 6.1/3.1A, with max heat dissipation of 447 BTU/hr using PoE+. Includes RPS and EPS input ports for redundancy.

What are typical deployment scenarios?

Suited for enterprise edge, remote branch offices, converged networks with VoIP/WLAN, and data center top-of-rack. High-performance architecture supports bandwidth-intensive apps with 10GbE uplinks for aggregation.
