HPE JL675A#ABA 48-Port Class 4 PoE Gigabit Switch with 4x SFP+ Uplinks

Overview

The HPE Aruba 6100 JL675A#ABA is a 1U rack-mountable Layer 3 gigabit switch purpose-built for deployments where you need to power and connect a large number of PoE devices — IP cameras, access control readers, VoIP phones, and wireless access points — without compromising on uplink throughput or management depth. Forty-eight 10/100/1000BASE-T PoE ports share a 370W power budget, and four SFP+ slots handle your uplinks to aggregation or core switches at 10 Gbps. If you are sizing a surveillance camera network or a converged IoT/security infrastructure, this switch slots cleanly into the access layer without requiring a separate PoE injector for every device on the floor.

Key Features

• 48 Class 4 PoE Ports (802.3af/at), 370W Budget: Class 4 PoE delivers up to 30W per port — enough for virtually every mainstream IP camera, PTZ, dual-band AP, or IP intercom on the market today. The 370W total budget translates to roughly 7.7W average per port across all 48, so plan your camera/AP mix against that ceiling. A deployment running 30 fixed cameras at ~6W each leaves headroom for PTZs or APs without tripping the budget.
• 4x SFP+ Uplink Slots (10 Gbps): Four 10GbE uplink slots let you push aggregated traffic to your core or NVR over fiber or a direct-attach copper cable, eliminating the 1GbE bottleneck that buries high-channel-count video recorders on older access switches. Fiber options mean you can span buildings or connect IDFs back to an MDF without distance constraints of copper.
• Layer 3 Switching: L3 capability means inter-VLAN routing runs on the switch itself — you can segment camera VLANs, management VLANs, and corporate data on the same hardware without routing everything back through a core router. For distributed security deployments, this reduces east-west camera traffic from crossing WAN links unnecessarily.
• 1U Rack-Mountable Form Factor: Standard 1U rackmount fits any 19-inch enclosure or rack cabinet. Wall-mount capability (also supported) is useful in IDF closets or camera head-end rooms where a full rack is not justified. At 30.6W idle power draw for the switch itself, it adds minimal load to UPS budgets.
• Gigabit on Every Access Port: Every one of the 48 access ports runs full gigabit — relevant when you are connecting multi-megapixel cameras recording at high bitrates, or mixing cameras with bandwidth-hungry APs. You will not hit a Fast Ethernet ceiling mid-deployment.
• Lifetime Warranty: HPE backs the 6100 series with a lifetime warranty, which eliminates the recurring cost of extended support contracts that typically accompany 3- or 5-year hardware warranties on competing access switches. For infrastructure that runs continuously, this materially affects total cost of ownership over a 7-to-10-year deployment horizon.
• Aruba 6100 Product Family: As part of the Aruba networking lineup, the 6100 integrates with Aruba Central for cloud-based management, AirWave for on-premises network monitoring, and supports ClearPass Policy Manager for role-based access control. If your organization already runs Aruba wireless, this switch fits the same management plane without adding a separate controller or NMS.

Integration and Compatibility

The JL675A#ABA operates as a standard managed Layer 3 switch and connects to any standards-compliant PoE device — IP cameras from Axis, Hanwha, Hikvision, i-PRO, Vivotek, and others all draw power and data from the same RJ-45 port. The four SFP+ slots accept standard SFP+ transceivers and DAC cables, giving you flexibility on the uplink side whether you are connecting to fiber backbone or a 10GbE-capable network video recorder directly.

For security-focused deployments, VLAN segmentation keeps camera traffic isolated from corporate endpoints — a straightforward configuration on an L3 switch that prevents cameras from being reachable on the general user network. 802.1X port authentication (supported at the L3 feature tier) adds an additional layer, requiring credentials before any device negotiates an IP address on a sensitive VLAN.

If you are planning a PoE infrastructure rollout, review our PoE switch selection guide to match total wattage requirements against your camera and AP mix before committing to switch count. The 370W budget is generous for a 48-port access switch, but high-power PTZ cameras at 25W each and multi-radio APs at 22W compress that headroom faster than fixed-dome cameras at 5-7W. Pairing this switch with compatible PoE switches at secondary IDFs is a common approach in multi-floor or multi-building deployments.

Frequently Asked Questions

Q: How many PoE devices can the JL675A#ABA realistically power simultaneously?

A: With a 370W PoE budget across 48 ports, the answer depends on per-device draw. Forty-eight standard IP cameras drawing 6-7W each would consume roughly 290-340W — within budget. Mix in PTZ cameras at 20-25W or dual-radio APs at 20-22W and you will need to calculate your actual wattage load. The switch enforces the 370W ceiling in hardware; ports that would exceed it do not power on until budget is available.

Q: Does the JL675A#ABA support 802.3at (PoE+) in addition to 802.3af (PoE)?

A: Yes. The switch is rated Class 4 PoE, which encompasses 802.3af (up to 15.4W) and 802.3at/PoE+ (up to 30W) on all 48 ports. Devices that negotiate lower power classes will draw less; devices requiring up to 30W (Class 4) are fully supported.

Q: What is the warranty on the JL675A#ABA?

A: HPE covers the Aruba 6100 series with a lifetime warranty. This applies to the hardware itself; software and support subscriptions are separate. Confirm specific terms with your HPE channel at time of purchase.

Q: Can the JL675A#ABA be wall-mounted rather than rack-mounted?

A: Yes. HPE lists both rack-mountable and wall-mountable as supported form factors for the 6100. Wall mounting is commonly used in IDF closets or head-end rooms where a full rack is not installed. Verify that appropriate mounting hardware is included or sourced separately before installation.

Q: Does the JL675A#ABA integrate with Aruba Central for cloud management?

A: The Aruba 6100 product family is designed to work within the Aruba management ecosystem including Aruba Central. Specific licensing requirements for cloud management features apply — consult current Aruba licensing documentation to confirm subscription requirements for your deployment scale.

Q: What SFP+ transceiver types are compatible with the JL675A#ABA uplink slots?

A: The four SFP+ slots support standard 10GbE SFP+ modules including short-range (SR) multimode fiber, long-range (LR) single-mode fiber, and 10G direct-attach copper (DAC) cables. HPE-branded transceivers are validated; third-party compatibility varies by firmware policy — verify before ordering non-HPE optics for production deployments.

The spec I always look at first on an access PoE switch is the ratio of total PoE budget to port count — and the JL675A#ABA lands at 370W across 48 ports, which is 7.7W average per port. That is a honest number for a mixed surveillance and wireless deployment: you have room to run the majority of your cameras at fixed-dome draw and still allocate 20-25W slots for the PTZs and APs without constantly tripping the power budget ceiling.

Technical Highlights:

• 370W PoE Budget / Class 4: Full 802.3at (30W) capability on every port means you are not guessing which ports can handle higher-draw devices — every port in the 48-port block is equal. That matters during moves-adds-changes when a PTZ replaces a fixed dome mid-deployment.
• 4x SFP+ at 10 Gbps: Four 10GbE uplinks on a 48-port access switch is the right ratio. You are not bottlenecked pushing multi-camera H.265 streams to an NVR or core switch — and the flexibility between SR fiber, LR fiber, and DAC means you can handle both in-rack and cross-building uplinks without changing the switch.
• Layer 3 with VLAN Routing: Inter-VLAN routing on the switch itself keeps camera traffic local to the access layer. In a distributed physical security deployment, that means your NVR pulls streams across the access switch rather than hairpinning through a core router — lower latency, less WAN exposure.

Deployment Considerations:

• Size your PoE budget before you finalize camera selection. If the project spec calls for a significant number of PTZ cameras (20-25W each) or tri-radio APs (25-30W), the 370W ceiling gets tighter than it looks on a 48-port switch — particularly if you factor in port-level power negotiation overhead.
• Third-party SFP+ transceiver compatibility is not guaranteed. HPE firmware on the 6100 series can flag non-HPE optics. If the project requires non-HPE transceivers, validate compatibility against the specific firmware revision before the switches are installed and cabled.

This switch is well-positioned for an IP camera access layer in a medium-to-large commercial building — 30 to 48 cameras per IDF, a mix of fixed domes and one or two PTZs per floor, with SFP+ fiber running back to a central NVR rack. The lifetime warranty removes one recurring line item from a deployment that is otherwise expected to run for a decade or more.
