What is the switching capacity and port configuration of HP 2920-48G?

HP 2920-48G (J9728A) offers 176 Gbps full-duplex switching capacity with 44x 10/100/1000BASE-T RJ-45 ports and 4 dual-personality ports (10/100/1000BASE-T or SFP). It achieves 130.9 Mpps throughput for non-blocking operation across all ports.

Does the 2920-48G support stacking and what are the benefits?

Yes, supports modular stacking of up to 4 switches via optional modules, managed as a single logical unit with unified IP address. This reduces management overhead, enhances resiliency with redundant paths, and scales port density to 192x 1G without additional controllers.

What latency performance does the HP 2920-48G provide?

Latency is <9.0 µs for 100 Mb and <3.3 µs for 1000 Mb FIFO 64-byte packets. This low-latency store-and-forward architecture suits real-time applications like VoIP and video in enterprise access layers.

Is the 2920-48G suitable for SDN deployments?

Powered by ProVision ASIC, it supports OpenFlow and progressive SDN programming, allowing gradual migration from traditional to software-defined networks without forklift upgrades. Ideal for customers planning Aruba Central integration.

What environmental tolerances does it have?

Operates at 32°F to 131°F (0°C to 55°C), 15-95% relative humidity noncondensing. Storage up to -40°C to 70°C, with altitude tolerance to 10,000 ft, suiting diverse branch and edge installations.

What routing and security features are included?

Supports static IPv4/IPv6 routing with 2048 IPv4/256 IPv6 host entries, 16000 MAC addresses. Security via ACLs, port security, DHCP snooping, and dynamic ARP protection for edge threat mitigation.

Product overview

The HP 2920-48G Switch (J9728A) is a high-performance, stackable Gigabit Ethernet switch designed for enterprise edge, SMB, and branch office deployments requiring secure, scalable networking. It features 44 fixed 10/100/1000BASE-T RJ-45 ports plus 4 dual-personality ports (10/100/1000BASE-T or SFP), enabling flexible copper or fiber connectivity. With 176 Gbps switching capacity and 130.9 million pps throughput, it handles demanding traffic with latency below 3.3 µs for 1000 Mb packets. Powered by a ProVision ASIC, it supports software-defined networking (SDN) roadmaps, modular stacking of up to 4 units for simplified management as a single logical device, and advanced features like sFlow, IPv4/IPv6 routing, and ACLs for security. Robust construction includes field-replaceable power supplies, 512 MB SDRAM, 1 GB flash, 11.25 MB packet buffer, and operation from 32°F to 131°F (0°C to 55°C). Ideal for access layer deployments, it reduces TCO through progressive architecture and eases migrations to Aruba solutions.
