HPE Aruba JL325A 2930 2-Port Stacking Module

The JL325A is a dedicated expansion module designed to enable high-performance stacking for the HPE Aruba 2930M series of Layer 3 switches. Its primary purpose is to physically interconnect multiple switches, allowing them to operate as a single, unified logical device. This solves a critical challenge in growing enterprise campus and branch networks: simplifying management and improving resiliency without requiring a complete infrastructure overhaul. By creating a cohesive fabric, it eliminates the complexity of managing individual switch configurations across wiring closets. At the core of this capability is Aruba’s Virtual Switching Framework (VSF) technology, which is unlocked by this module. VSF allows network administrators to stack up to ten 2930M switches, creating a high-bandwidth, resilient backplane between them. This architecture ensures that if one switch or link in the stack fails, traffic is automatically rerouted through the remaining units, providing seamless failover and maintaining network uptime. This deep integration is crucial for supporting mission-critical applications that demand constant availability. Physically, this unit is a hot-swappable plug-in module that installs into a dedicated stacking slot on the rear of any 2930M switch. Its compact form factor requires no additional rack space, making it a simple and efficient upgrade. Once installed and connected with the appropriate stacking cables, the entire stack is managed via a single IP address, dramatically simplifying administration tasks like firmware updates, policy deployment, and network monitoring through platforms like Aruba Central or a command-line interface (CLI).
