What PoE capabilities does the HPE Aruba J9729A#ABA provide?

The J9729A#ABA Aruba 2920 48G PoE+ Switch supports IEEE 802.3at PoE+ on 48x 10/100/1000BASE-T ports with a 380W power budget. It prioritizes power allocation via LLDP and SNMP, suitable for powering up to 48 Class 3/4 devices like APs and phones while maintaining QoS for voice/video traffic.

What is the switching performance of the Aruba 2920 J9729A#ABA?

It delivers 176 Gbps full-duplex switching capacity across 48 Gigabit ports and 4 SFP uplinks, ensuring wire-speed non-blocking forwarding. Supports jumbo frames up to 9220 bytes and 8 QoS queues per port for low-latency handling of high-bandwidth applications in access networks.

Does the J9729A#ABA support switch stacking?

Yes, via Virtual Switching Framework (VSF) stacking up to 4 units, creating a single logical switch with unified management. Stacking uses front-panel ports for up to 40 Gbps inter-switch links, enhancing redundancy and scalability in campus access deployments.

What management features are available on this switch?

Runs HPE ProVision OS with CLI, Web UI, SNMP, and Zero Touch Provisioning (ZTP). Supports VLANs (256 max), ACLs (up to 2K IPv4), RIP/OSPF stub routing, OpenFlow 1.3 for SDN, and integration with Aruba AirWave or Central for centralized monitoring.

Is the J9729A#ABA suitable for replacing older PoE switches?

Yes, as a direct replacement for Aruba 2915 series, it offers higher PoE budget (380W vs lower), more ports, and advanced features like VSF. However, note its end-of-sale status; consider 2930F/M series for new deployments with modular uplinks and higher PoE.

What uplink options does the Aruba 2920 48G PoE+ offer?

Four dual-personality RJ-45/SFP ports support 1G copper or fiber uplinks. Compatible with SFP transceivers for multimode/single-mode fiber up to 10km, enabling flexible aggregation to 10G core switches in enterprise hierarchies.
