HP JL356AHP Aruba 2540 24G PoE+ 4SFP+ JL356A Managed Switch Rack Mount Enterprise

Key Benefits

• 24 x PoE+ Gigabit ports, 370W budget: Power wireless access points, IP phones, and cameras across a complete SMB access layer from a single 1U switch.
• 4 x SFP+ uplinks (1G/10G-capable): 10G uplink capacity prevents bottlenecks when all 24 access ports are active — ideal for converged data, voice, and video networks.
• VLAN, QoS, and access control: 802.1Q VLANs for traffic segmentation, QoS prioritisation for voice and video, and 802.1X port authentication for network access control.
• Static routing built in: Route between VLANs without a dedicated router — simplifies small enterprise topology and reduces hardware costs.
• Simple web and CLI management: Intuitive web interface and full CLI access make it easy to configure and monitor without specialist training.
• Certified refurbished with 12-month warranty: Professionally tested and graded by Reboot IT — Melbourne's refurbished networking specialists since 2001.

Performance in Use

The HP Aruba 2540 24G PoE+ 4SFP+ (JL356A) is a smart-managed access switch designed for SMB and small enterprise environments where PoE, VLANs, and 10G uplinks are required without the complexity of a full enterprise platform. With 24 PoE+ Gigabit ports and 370W of shared power, it comfortably handles a mixed deployment of Aruba or Cisco wireless APs (15–25W), IP desk phones (4–6W), and IP cameras — all from a single 1U rack unit.

The four SFP+ ports are a standout feature at this price point. Running 10G DAC cables or SFP+ fibre modules to an aggregation or core switch eliminates the single-Gigabit uplink bottleneck that affects lower-tier switches when all 24 access ports are active. LACP allows two of these uplinks to be bonded for active-active redundancy — critical for environments where the switch is a single point of failure for multiple VoIP phones or security cameras.

The 2540's static routing capability allows inter-VLAN routing locally on the switch, avoiding the need for a separate router in smaller deployments. Combined with DHCP snooping, Dynamic ARP Inspection, and 802.1X, it provides a comprehensive security posture appropriate for a small enterprise. Management via web GUI, CLI, or SNMP makes it accessible to both IT generalists and network specialists.

Frequently Asked Questions

How does the 2540 differ from the 2930F and 2930M?

The 2540 is a smart-managed switch with static routing only, while the 2930F and 2930M are full Layer 3 switches supporting OSPF and RIP dynamic routing. The 2540 is simpler and more cost-effective for SMB access layers where dynamic routing is not required.

Are the SFP+ ports 10G capable?

Yes — all four SFP+ uplink ports support both 1G SFP and 10G SFP+ modules. Using 10G modules eliminates uplink bottlenecks when all 24 access ports are heavily loaded.

Can all 24 ports deliver PoE+ simultaneously?

The 370W shared budget supports simultaneous PoE on all 24 ports in typical mixed deployments. Powering high-draw devices such as PTZ cameras (25W each) across all ports simultaneously would approach the 370W limit and should be planned accordingly.

Does the 2540 support VLAN routing?

Yes — the JL356A supports inter-VLAN static routing, allowing traffic to flow between VLANs directly on the switch. Dynamic routing protocols (OSPF, RIP) are not supported.

Does it support link aggregation (LACP)?

Yes — the 2540 supports IEEE 802.3ad LACP, allowing multiple SFP+ ports to be bonded for increased uplink bandwidth or active-active redundancy.
