Aruba CX 6300M (JL660A) — 24× 1G PoE+ access with 4× SFP56 uplinks (1/10/25/50G)

What it is: A Layer-3, stackable access switch with 24 × 10/100/1000 RJ-45 PoE+ ports and 4 × SFP56 uplinks (supporting 1/10/25/50G), running AOS-CX. You get hot-swappable dual PSU bays and a hot-swap fan tray, so you can service power/cooling without taking the closet down.

Why buyers pick JL660A (plain English)

• Right-sized PoE for smaller closets: 24 PoE+ ports for APs/phones/cameras without overbuying density.

• Uplink headroom: 4× SFP56 cages for 25/50G to aggregation or stack—no bottleneck after a Wi-Fi 6/6E refresh.

• Service live: dual hot-swap PSUs and hot-swap fan keep users online during maintenance.

• Unified ops: AOS-CX with Network Analytics Engine, Switch Multi-Edit, and Aruba Central management—same workflows as the rest of CX.

60-second spec box (JL660A)

Access ports

• 24 × 10/100/1000 RJ-45, IEEE 802.3at Class 4 PoE+

Uplinks (built-in)

• 4 × SFP56 cages supporting SFP/SFP+/SFP28/SFP56 (1/10/25/50G)

• Also used for front-plane VSF stacking

Power / cooling

• Two hot-swap PSU bays (order 1–2)

• Hot-swap fan tray (field-replaceable)

PoE budget (typical options)

• Scales with PSU choice; common supplies: 680W, 1050W, or 1600W.

• Design for your endpoint draw plus 20–30% headroom.

Stacking / HA

• VSF stacking (front-plane over uplinks), single-IP management, fast failover; large multi-unit stacks supported

Software & features

• AOS-CX, NAE (Network Analytics Engine), REST APIs/Ansible, ACLs/QoS, OSPF/Static, Dynamic Segmentation, Central/AirWave support

Form factor

• 1U rack-mount; enterprise build, field-serviceable modules

What to order with it (common BOM adds)

• Power supplies: pick wattage for your PoE plan (e.g., 680W for light AP/phone floors, 1050W/1600W for camera-heavy floors). Add a second PSU for redundancy.

• Fan tray: spare recommended for mission-critical sites.

• Optics/cables: SFP+/SFP28/SFP56 (SR/LR) or DAC/AOC to match 10/25/50G uplinks/stack links.

• Aruba Central subscription if you want cloud management and AIOps.

Where it fits (and when to step up/down)

• Perfect for: branch/campus access with a moderate number of powered endpoints and 25/50G uplink needs.

• Step down to CX 6200M if 10G SFP+ uplinks are enough and you want a lower price point.

• Step up to CX 6300M 48-port (JL661A) if you need more PoE density on a single switch.

TL;DR

JL660A gives you 24× 1G PoE+ at the edge with four 1/10/25/50G SFP56 uplinks, hot-swap PSUs/fan, and the AOS-CX ops experience—ideal for modern access layers that want PoE now and uplink headroom for tomorrow.
