Aruba JL658A — CX 6300M 24×10G SFP+ + 4×SFP56 (25/50G) stackable aggregation/access switch

What it is: An Aruba CX 6300M Series switch built for enterprise access, aggregation, or collapsible core. JL658A gives you 24 × 1/10G SFP+ ports for fiber access or server edge, plus 4 × SFP56 high-speed ports that run 1/10/25/50G for uplinks or stacking. Runs AOS-CX, so it feels like the rest of the CX family and is automation/telemetry-first.

Why buyers pick JL658A (plain English)

• “All-fiber edge” in one box: 24 SFP+ ports are perfect for campuses moving to fiber desks, AP closets, or ToR 10G servers.

• Fast uplinks without a bigger chassis: the 4 SFP56 ports let you push 25G/50G to aggregation or core.

• Easy scale with stacking: built for VSF stacking, so multiple switches act like one and upgrades don’t hurt.

• Modern CX operations: AOS-CX gives you NAE analytics, REST APIs, and Aruba Central support.
