Aruba JL659A — CX 6300M 48×10G SFP+ + 4×SFP56 (25/50G) stackable aggregation/access switch

What it is: An Aruba CX 6300M Series switch aimed at enterprise access, aggregation, or collapsible core roles. JL659A is the bigger fiber sibling to the 24-port model: you get 48 × 1/10G SFP+ ports for high-density fiber access or ToR servers, plus 4 × SFP56 ports that run 1/10/25/50G for uplinks or VSF stacking. Runs AOS-CX, so operations stay consistent with the rest of your CX network.

Why buyers pick JL659A (plain English)

• High-density “all-fiber edge”: 48 SFP+ ports is ideal for fiber-to-the-desk, AP closets, or server rows.

• Fast uplinks without jumping to a core chassis: 4 SFP56 ports give you clean 25/50G uplinks to agg/core.

• Easy scale with stacking: VSF stacking makes multiple switches behave like one, simplifying growth and updates.

• Modern CX operations: AOS-CX brings Network Analytics Engine, REST APIs, and Aruba Central support.

Access / downlink ports

• 48 × SFP+ supporting 1G / 10G

High-speed uplinks / stacking

• 4 × SFP56 supporting 1G / 10G / 25G / 50G

• Commonly used for uplinks or VSF stack links

Stacking / HA

• VSF (Virtual Switching Framework), typically up to 10 members

• Stack over SFP56 for high-bandwidth front-plane stacking

Performance (model typical)

• Enterprise-class line-rate switching, sized for full 10G edge with 25/50G uplinks

• (Think “aggregation-ready” throughput in a 1U access form factor.)

OS & management

• AOS-CX with NAE analytics, automation-first design

• Managed via CLI/Web UI, Aruba Central, telemetry/SNMP

Resiliency

• Dual hot-swap PSUs (1+1 redundancy capable)

• Hot-swap fan trays

• Built for always-on wiring-closet duty

Form factor

• 1U rack-mount, fixed depth, data-center/closet friendly

Where it fits (and when to choose something else)

• Perfect for:

  • High-density fiber access floors (lots of 10G SFP+ endpoints)

  • Aggregation where you want 25/50G uplinks in a compact 1U

  • Collapsed core at mid-size sites using VSF stacks

• Choose JL658A if you want the same idea with 24 SFP+ instead of 48.

• Choose CX 6300F if you want fixed-PSU models at a lower cost.

• Choose CX 8325/8360 if you’re going 25G/100G-dense at core/DC scale.

TL;DR

JL659A = CX 6300M 48SFP+ 4SFP56: a high-density, fiber-first, stackable CX switch with 48×1/10G SFP+ plus 4×25/50G uplinks/stacking, AOS-CX ops, and hot-swap resiliency — the “big closet” option when you want a serious 10G edge with faster uplinks baked in.
