Overview

The HP JG928A belongs to the ProCurve 1920 Switch Series, a line of smart-managed switches aimed at organizations that need more than basic unmanaged switching but do not require the full depth of an enterprise-managed platform. With 48 Gigabit Ethernet ports and four SFP slots, the JG928A provides substantial connectivity in a single rack-mount unit. Its 370W PoE+ budget means you can power access points, IP phones, security cameras, and other PoE-compatible devices directly through the Ethernet cable, reducing cabling clutter and eliminating the need for individual power adapters.

Management is handled through a web-based interface that gives administrators access to VLANs, Quality of Service policies, port mirroring, and IPv6 configuration. This makes the JG928A practical for segmented networks where traffic prioritization matters — for example, keeping VoIP traffic on a dedicated VLAN with guaranteed bandwidth. The SFP ports support fiber uplinks for connections to core switches or between floors and buildings. For small to mid-sized deployments where PoE+ is a priority and full enterprise management would be overkill, the JG928A delivers a strong balance of features, port density, and power delivery.

Key Features

HP JG928A ProCurve 1920-48G-PoE+ - 4 x SFP, 48 x 10/100/1000Base-T

The HP 1920 Switch Series, part of the HP OfficeConnect portfolio, is designed for smaller organizations dealing with bandwidth-demanding applications. The switches are ideal for environments that require advanced features for granular control and where smart-managed flexibility is a must for easy network configuration and management.

The switches deliver advanced smart-managed fixed configuration Gigabit switches that build on the marketing-leading price/performance of the HP 1910 Switch Series. They feature a new 48-port PoE+ model, IPv6 support and advanced silicon technology.

Pros & Cons

👍 Pros

  • 48 Gigabit ports plus 4 SFP uplinks provide ample connectivity for small to mid-sized networks
  • 370W PoE+ budget powers IP cameras, access points, and VoIP phones without separate power supplies
  • Smart-managed interface offers VLANs, QoS, and IPv6 without the complexity of full enterprise management
  • Fanless or low-noise design typical of the 1920 series suits office environments

👎 Cons

  • 370W PoE budget may be insufficient if many high-draw devices like PTZ cameras are connected simultaneously
  • Smart-managed feature set lacks the full CLI and advanced routing of fully managed enterprise switches
  • No 10-Gigabit uplink ports, which may bottleneck networks with heavy aggregated traffic
  • The unit's 48-port form factor requires a standard 19-inch rack and adequate ventilation

Frequently Asked Questions

The switch provides a total PoE+ budget of 370W distributed across its 48 Gigabit ports. Individual ports support up to 30W under the PoE+ (802.3at) standard.
The four SFP (Small Form-factor Pluggable) ports allow you to connect fiber optic uplinks or stack switches together, extending your network beyond copper cabling distances.
The JG928A is a smart-managed switch. It provides advanced features like VLANs, QoS, and IPv6 support through a web-based interface, but does not include the full CLI management of an enterprise-managed switch.
Yes, the JG928A includes IPv6 support, making it suitable for networks that are transitioning to or already using IPv6 addressing.
You can connect PoE devices to all 48 ports, but the total power draw cannot exceed the 370W budget. If every device draws maximum PoE+ power (30W), you would be limited to around 12 fully powered devices, with the remaining ports providing data only.
