HPE JL325A Aruba 2930 2 Port Stacking Module

Purpose and Fit

The HPE JL325A Aruba 2930 2 Port Stacking Module adds two dedicated stacking ports to compatible Aruba 2930 Series switches. It is designed for network administrators who need to manage multiple physical switches as a single logical unit. This module suits environments that require simplified management and increased port density without using standard uplink ports for inter-switch links.

Upgrade Context

The module replaces the need to use front-panel SFP or SFP+ ports for switch-to-switch stacking connections. The jump is worthwhile when you want to preserve all uplink ports for server or storage traffic while gaining a resilient stacking backbone. It is not for buyers who need stacking on non-2930 platforms or who require more than two stacking links per switch.

Installation Notes

The module installs into the rear expansion slot of a supported Aruba 2930 Series switch and is hot-pluggable, so the switch stays online during installation. Common issues include inserting the module into an incompatible switch model or forgetting to enable stacking in the switch operating system after the hardware is seated. Always verify the switch model matches the compatibility list before purchase.
