Aruba CX 8400X-32Y 32p 1/10/25G SFP/SFP+/SFP28 Module

The Aruba JL687A is a 32-port module for the Aruba CX 8400 switch chassis that adds high-speed fiber connectivity without changing your existing platform. Each slot accepts an SFP, SFP+, or SFP28 transceiver, letting you run 1, 10, or 25 gigabit links on the same hardware. If you are expanding a data center fabric, upgrading an enterprise core, or segmenting traffic for demanding workloads such as virtualization and storage, this module supplies the bandwidth headroom you need while protecting your investment.

Installation is straightforward: the module slides into any open slot of the eight-slot Aruba 8400 chassis and comes online after a simple software recognition process. Because it relies on optical fiber and supports 25GBase-X technology, you can push large data flows across longer distances with lower latency and less electromagnetic interference than copper alternatives. The plug-in approach also keeps your rack organized, since the module measures about 16.6 by 11.9 by 1.7 inches and weighs roughly 10.7 pounds, so you gain 32 extra ports without consuming additional rack units.

Network teams that plan for future growth will appreciate the flexibility. You can start with lower-speed optics today, migrate to faster 25 gigabit transceivers later, and do it all in the same chassis slot. This makes the JL687A a practical choice for campus backbones, aggregation layers, or any environment where scalable fiber capacity matters.
