Aruba JL662A — CX 6300M 48× Smart Rate mGig + 60W PoE with 4× SFP56 (25/50G) uplinks

What it is: An Aruba CX 6300M Series switch designed for high-density modern access. JL662A is the 48-port Smart Rate PoE monster: 48 HPE Smart Rate copper ports (1/2.5/5G) delivering Class 6 PoE up to 60W/port, plus 4 × SFP56 uplinks that run 1/10/25/50G for fast core links or VSF stacking. Runs AOS-CX, same operating model as the rest of your CX network.

Why buyers pick JL662A (plain English)

• Wi-Fi 6/6E/7 ready at scale: 48 mGig ports means you can feed lots of high-throughput APs without a 1G bottleneck.

• No injector life: 60W PoE covers heavy-draw APs, PTZ cams, displays, IoT/lighting, and whatever the building throws at you next.

• Real uplink horsepower: SFP56 lets you jump straight to 25/50G aggregation or use them as fat VSF stack links.

• Stack and forget: VSF makes multiple switches act like one—simple growth, cleaner upgrades.

• Modern CX ops: AOS-CX brings built-in analytics (NAE), automation, and Aruba Central management.

OS & management

• AOS-CX with Network Analytics Engine, REST APIs, automation-first design

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

Resiliency

• Dual hot-swap PSUs (1+1 redundancy capable; PoE budget depends on PSU choice)

• Hot-swap fan trays

Form factor

• 1U rack-mount, fixed-depth chassis

Where it fits (and when to choose something else)

• Perfect for:

  • Big access closets with lots of Wi-Fi 6/6E/7 APs or dense IoT

  • Floors needing 5G copper without rewiring to fiber

  • Sites that want 25/50G uplinks from access to aggregation/core

• Choose JL660A if you want the same idea in 24 ports instead of 48.

• Choose JL658A/JL659A if you want all-fiber 10G SFP+ access.

• Choose CX 6300F if hot-swap PSU/fan modularity isn’t needed and you want a lower-cost fixed-hardware option.

TL;DR

JL662A is the high-density mGig + big-power CX 6300M: 48× 1/2.5/5G Smart Rate copper with 60W PoE, plus 4× 25/50G SFP56 uplinks/stacking, all running AOS-CX with hot-swap resiliency. Ideal when your edge needs speed and serious PoE at scale.
