Aruba JL624A — CX 8325-48Y8C, high-density 25G/100G core + ToR switch

What it is: An Aruba CX 8325 Series switch built for campus core/aggregation or data-center top-of-rack. JL624A is the 48Y8C model: lots of 25G SFP28 downlinks plus 100G QSFP28 uplinks, all running AOS-CX with deep telemetry and modern automation.

Why buyers pick JL624A (plain English)

• Massive port density in 1U: run a 25G edge with 100G uplinks without burning racks.

• Core + DC flexible: equally at home as a campus aggregation/core box or a leaf/ToR.

• Future-proof bandwidth: 25G/100G gives you tons of headroom for Wi-Fi 6/7, servers, EVPN fabrics, or high-speed distribution.

• Same AOS-CX brain as the rest of CX: consistent ops, NAE analytics, and Aruba Central support.
