JL081A - Aruba 3810M/2930M Smart Rate PoE+ Module

Aruba JL081A — 4-Port Smart Rate (1/2.5/5/10G) PoE+ Expansion Module for 3810M / 2930M

What it is

JL081A isn’t a switch — it’s an add-on module.
It’s a 4-port HPE Smart Rate expansion module made for Aruba 3810M and 2930M modular switches. You slide it into the module slot to add four copper multigig ports that support 1G, 2.5G, 5G, and 10G, and each port can deliver PoE+. Think “upgrade your access switch with a small block of high-speed PoE multigig for Wi-Fi APs.”

Why buyers pick JL081A (plain English)

• Multigig for modern Wi-Fi without a new switch
  Great when your 3810M/2930M is fine, but your APs want more than 1G.

• PoE+ built in on all four ports
  Powers Wi-Fi 5/6/6E APs, phones, cameras, or IoT right from the module.

• Flexible speed per port
  Auto-negotiates 1/2.5/5/10G so you can mix device types.

• Clean, supported Aruba upgrade path
  First-party module that keeps your chassis fully supported and consistent.

• Aruba 3810M Series

• Aruba 2930M Series

Install

• Field-installable, hot-insertable module (best practice: insert during maintenance window)

Where it fits (and when to choose something else)

Perfect for:

• Adding a small number of multigig PoE ports for high-throughput APs

• Extending life of existing 3810M/2930M deployments

• Edge closets upgrading to Wi-Fi 6/6E without forklift swaps

Choose something else if:

• You need lots of multigig ports across the closet → consider a newer CX access switch lineup

• You don’t need PoE → a non-PoE multigig module (if available for your chassis) may be cheaper

TL;DR

JL081A is a 4-port Smart Rate PoE+ module for Aruba 3810M/2930M:
adds 4× copper ports that run 1/2.5/5/10G and power devices via PoE+ — ideal for multigig Wi-Fi AP uplinks without replacing your switch.
