Aruba JL664A — CX 6300M 24×1G copper + 4×SFP56 (25/50G) stackable access/aggregation switch

What it is: An Aruba CX 6300M Series fixed-port switch built for enterprise access, aggregation, collapsible core, or even data-center OOB/ToR. JL664A gives you 24 × 1GbE RJ-45 access ports (data) and 4 × SFP56 high-speed ports that run 1/10/25/50G for uplinks or VSF stacking. Runs AOS-CX, so you get modern telemetry, automation, and consistent ops across the CX family.

Why buyers pick JL664A (plain English)

• A tidy 1G edge with fast uplinks: keep copper to endpoints, but uplink at 25/50G so the closet isn’t the choke point.

• Compact fiber/agg add-on: great when you need just 24 copper ports plus serious uplinks.

• Stacks simply: VSF stacking makes multiple switches behave like one—easy growth, clean upgrades.

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

  • Copper-heavy floors (desktops/printers/phones) with modern campus backbones

  • Aggregation/OOB roles where 24 access ports is the right density

• Choose JL661A if you need the same 24×1G layout with PoE+.

• Choose JL663A if you want 48×1G copper instead of 24.

• Choose JL660A/JL662A if you need Smart Rate mGig + 60W PoE for AP-heavy floors.
