JL084A - Aruba 3810M 4-port Stacking Module

HPE Aruba JL084A — Aruba 3810M 4-Port Stacking Module

What it is

JL084A is an HPE Aruba 3810M Series stacking module that enables high-speed, resilient stacking between Aruba 3810M switches.
It adds 4 dedicated stacking ports per module, allowing multiple switches to operate as a single logical unit with simplified management and higher overall throughput.

Why buyers pick JL084A (plain English)

True stack convergence
Creates a single logical stack across multiple 3810M switches, simplifying management and configuration.

High-speed stacking links
Dedicated stacking ports ensure stack bandwidth isn’t shared with regular network traffic, improving responsiveness.

Resilient architecture
Stack redundancy and automatic failover keep traffic flowing even if a member switch has issues.

Scales access networks
Ideal for enterprise campus or branch deployments needing unified switch stacks rather than independent devices.

Aruba-validated reliability
Designed and tested to work specifically with Aruba 3810M Series hardware for predictable behavior and support.

Where it fits (and when to choose something else)

Perfect for:

• Stacking Aruba 3810M switches into a single logical unit

• Campus access and distribution stacks

• Environments needing simplified multi-switch management

• Redundant and resilient network edge designs

Choose something else if:

• You’re using standalone switches → stacking not required
