J9988A - Aruba 24-port 1GbE SFP MACsec v3 zl2 Module

Aruba J9988A — 5400R zl2 24-Port 1GbE SFP MACsec v3 zl2 Module

What it is

J9988A isn’t a switch or optic — it’s a chassis line module.
It’s the 24-port 1GbE SFP MACsec v3 zl2 expansion module for the Aruba 5400R zl2 Series chassis (5406R zl2 / 5412R zl2). You install it in a zl2 module slot to add twenty-four 1G SFP fiber ports, with hardware MACsec so you can encrypt links at line rate.

Why buyers pick J9988A (plain English)

• High-density 1G fiber in one slot
  Perfect when a 5400R chassis needs lots of gigabit SFP ports for access uplinks or distribution fiber.

• MACsec built in for secure links
  Encrypts switch-to-switch or switch-to-server connections without performance hit.

• Flexible optics support
  Works with standard 1G SFP optics (SX/LX/EX/etc.) to match campus fiber needs.

• Hot-swappable chassis module
  Adds capacity or replaces a module cleanly in HA chassis setups.

  • 5406R zl2

  • 5412R zl2

Install / service

• Slot-based, hot-swappable module

• Best practice: redundant management + PSUs for hitless maintenance

Where it fits (and when to choose something else)

Perfect for:

• 5400R zl2 cores/distribution needing lots of 1G fiber ports

• Campus backbones feeding many access closets

• Environments requiring secure MACsec gigabit uplinks

Choose something else if:

• You need 10G ports instead → use an SFP+ zl2 module

• You need 40G/100G uplinks → use QSFP(+/28) zl2 modules

• You’re not on a 5400R zl2 chassis → this module won’t fit

TL;DR

J9988A is the 5400R zl2 “24-port 1G SFP fiber module with MACsec”:
adds twenty-four gigabit SFP ports plus hardware MACsec v3 for secure, high-density fiber connectivity in a 5400R zl2 chassis.
