What is the PoE capability and budget of the HPE JL428A#ABA?

The Aruba 3810M JL428A#ABA provides full PoE+ (IEEE 802.3at) on all 48x 10/100/1000BASE-T RJ-45 ports with a 680W power budget from the internal hot-plug supply. This supports high-power devices like 802.11ac access points and PTZ cameras simultaneously, with dynamic power allocation and prioritization via QoS.

What switching performance does the JL428A#ABA deliver?

It offers 480Gbps routing/switching capacity, 508Gbps fabric bandwidth, and up to 285.7 Mpps throughput for 64-byte packets. Latency is <2.8µs (1G), <1.8µs (10G), <1.5µs (40G capable via modules), ensuring non-blocking wire-speed forwarding across all ports in stacked configurations.

Does the switch support stacking and resiliency features?

Yes, it includes one stacking module slot for backplane stacking up to 40Gbps inter-switch links. Resiliency features VRRP, redundant hot-plug PSUs (1+1), spanning tree protocols (STP/PVST), LACP, and bidirectional forwarding detection (BFD) for high availability in enterprise deployments.

What management and security protocols are supported?

Management via SNMPv1-3, RMON 1-3/9, SSHv2, CLI, HTTP, XRmon. Security includes RADIUS/TACACS+, 802.1X, ACLs, SSL encryption, dynamic VLAN (GVRP/MVRP), and OpenFlow for SDN integration, providing comprehensive access control and monitoring.

Is the JL428A#ABA suitable for high-density Wi-Fi deployments?

Yes, with 48x PoE+ ports at 30W each (680W total), HPE Smart Rate multi-gigabit compatibility for 802.11ac devices, low latency, and robust QoS with CoS/TOS marking. It excels in aggregating APs in campus or branch environments with line-rate 10G uplinks.

What expansion options does it offer?

Four 10G SFP+ expansion slots for fiber/copper uplinks, one stacking module slot, plus console (RJ-45/serial), OOB management (RJ-45), and micro-USB ports. Supports jumbo frames, sFlow v5, and MLD for multicast optimization.

Product overview

The HPE Aruba JL428A#ABA (Aruba 3810M 48G PoE+ 4SFP+ 680W Switch) is a high-performance Layer 3 managed stackable switch designed for enterprise, SMB, and branch office networks. It features 48x 10/100/1000BASE-T PoE+ RJ-45 ports delivering up to 680W PoE budget for powering high-density Wi-Fi APs, IP cameras, and VoIP phones. Four 10G SFP+ bays and one stacking module slot enable high-speed uplinks and resilient backplane stacking up to 480Gbps switching capacity with 508Gbps fabric bandwidth. Low latency (<2.8µs at 1G, <1.8µs at 10G) ensures optimal application performance. Advanced features include OSPF, IPv6 BGP, VRRP, robust QoS, policy routing, OpenFlow, sFlow, and full PoE+ on all ports without licensing. Dual hot-plug redundant power supplies (1+1) provide resiliency in a compact 1U rack form factor. Ideal for aggregating access switches, supporting 802.11ac devices, virtualization, and scalable campus/branch topologies with IPv4/IPv6 routing tables up to 10K/5K entries.
