Aruba JL667A — CX 6300F 48×1G copper + 4×SFP56 (25/50G) stackable access/aggregation switch

What it is: An Aruba CX 6300F Series fixed-port switch for enterprise access, aggregation, or collapsible core. JL667A gives you 48 × 1GbE RJ-45 data ports (no PoE) plus 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 JL667A (plain English)

• Classic 1G edge, modern uplinks: keep copper to endpoints, but uplift the closet with 25/50G to core/agg.

• High-density access without PoE cost: great for desks, printers, thin clients, and non-powered IoT.

• Stacks cleanly: VSF makes multiple switches act like one—easy scaling and tidy upgrades.

• 6300F value play: CX features and performance in a simpler fixed-hardware cost profile.

OS & management

• AOS-CX (Network Analytics Engine, REST APIs, automation-first)

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

• USB-C console, OOB management port, USB-A host

Hardware profile (6300F trait)

• Fixed internal PSU (not hot-swap modular like 6300M)

• Fixed internal fans

• Built for reliable wiring-closet duty

Form factor

• 1U rack-mount, fixed depth

Where it fits (and when to choose something else)

• Perfect for:

  • High-density 1G access closets with fast uplink needs

  • Copper floors where PoE isn’t required

  • Aggregation of multiple 1G blocks into 25/50G core links

• Choose JL663A if you want the same idea in 6300M with hot-swap PSUs/fans.

• Choose JL668A/JL669A (PoE+) if you need powered access ports.

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

TL;DR

JL667A is the CX 6300F “48 copper + fast uplink” workhorse: 48×1G RJ-45, 4×SFP56 up to 50G, VSF stacking, and AOS-CX analytics/automation — a strong, no-drama pick for modern 1G access or compact aggregation.
