Frequently Asked Questions
What is the total PoE+ power budget for the HPE 2920-48G-PoE+ switch? +
The J9729-61001 provides a robust PoE+ power budget designed to support high-density deployments of IP phones, wireless access points, and surveillance cameras. It delivers up to 370W of total Power over Ethernet capacity, ensuring consistent power delivery across all 48 ports according to IEEE 802.3at standards, making it an ideal choice for power-hungry edge device environments.
Does the HPE 2920-48G-PoE+ support stackable configurations? +
Yes, this switch supports stacking through the dedicated stacking modules located on the back of the unit. You can stack up to four 2920 switches together, which allows for simplified management and increased port density. This architecture provides a single IP address for the entire stack, significantly reducing the administrative overhead in growing enterprise networks.
What kind of uplink options are available for the J9729-61001? +
The HPE 2920-48G-PoE+ offers flexible connectivity options through its expansion slots. It supports optional modules that provide 10GbE SFP+ or additional 1GbE SFP ports. This modularity allows network administrators to adapt the switch to evolving bandwidth requirements, enabling high-speed uplinks to the core layer without needing to replace the entire switch infrastructure.
Can the J9729-61001 perform Layer 3 routing functions? +
This unit is a fully managed Layer 3 switch that supports static and RIP routing. It is specifically designed to handle inter-VLAN routing and basic traffic segmentation at the access or aggregation layer. By offloading these routing tasks from the core, it optimizes network traffic flow and improves overall latency for time-sensitive enterprise applications.
How is the J9729-61001 managed and configured? +
Management is handled through a variety of intuitive interfaces, including an industry-standard CLI, a secure web-based GUI, and SNMP support for integration with broader network management platforms. These tools provide comprehensive control over VLAN configurations, PoE scheduling, and security policies, ensuring the switch can be precisely tuned to meet specific operational requirements.
Is the HPE 2920-48G-PoE+ suitable for voice-over-IP deployments? +
Absolutely. The switch includes features like LLDP-MED and auto-voice VLAN, which automatically prioritize and configure voice traffic. These capabilities ensure high-quality, jitter-free performance for IP phones, while the integrated PoE+ capabilities eliminate the need for separate power injectors, streamlining your deployment and reducing physical clutter in your wiring closets.
What security features does this switch offer to protect the network edge? +
Security is a primary focus, with support for IEEE 802.1X, MAC-based authentication, and Web-based authentication. Additionally, the switch features ACLs for granular traffic filtering and storm control to prevent network congestion. These multi-layered security protocols ensure that only authorized devices can access your network, effectively mitigating risks from unauthorized entry points.
What is the switching capacity of the HPE 2920-48G-PoE+? +
The J9729-61001 is built for high-performance enterprise environments with a switching capacity of up to 176 Gbps. This allows it to handle heavy traffic loads across all 48 ports simultaneously without bottlenecks. Its architecture ensures non-blocking performance, which is critical for demanding applications like video streaming and large file transfers within the corporate LAN.
