Aruba CX Series Factory Reset (6100, 6200, 6300, 6400): The IT Administrator’s Complete Guide

What do you do when a critical Aruba CX 6200 switch in a remote office is locked, and your deployment deadline is tomorrow? Or perhaps you just received a refurbished Aruba 6300, and the previous admin credentials are lost. For IT administrators, network engineers, and system integrators, these scenarios are all too common.
Restoring your Aruba CX 6100, 6200, 6300, or 6400 Series switch to factory default is often the fastest way to regain control, validate equipment for redeployment, or prepare for new branch installations. However, the AOS-CX operating system changes the reset procedure compared to older ProVision switches—there is no dedicated hardware reset button, and understanding CLI commands or the Service OS (SVOS) is crucial to avoid mistakes.
Before proceeding, remember that a factory reset erases all saved configurations including VLANs, ACLs, static IPs, security settings, and PoE assignments. Always back up your configurations if possible.

Part 1: Why the Physical Button Won’t Work on Aruba CX

Unlike older switches like the 2930F or 2620 series, the CX series does not have a physical factory default button. The Reset button on the front panel only reboots the device:

• Short press: software reboot
• Long press: hardware reboot

All true factory resets on CX series switches must be executed via CLI or Service OS.

Part 2: CLI Factory Reset – Standard Method for AOS-CX

If you have CLI access, this is the most reliable way to reset a CX switch to factory defaults. Ideal for batch deployments and preparing refurbished devices.

Steps to Perform CLI Factory Reset

1. Connect via console port (recommended speed: 115,200).
2. Execute the command:

Aruba-CX-Switch# erase all zeroize

3. Confirm the operation (`y`). The system will erase all management module files (except software images) and reboot.
4. Post-reset login is typically admin with a blank password. The system will prompt for a new password immediately.

This procedure works across Aruba 6100, 6200, 6300, and 6400 models.

Part 3: Password Recovery – When You Are Locked Out

If you only lost the admin password, do not perform a full factory reset immediately. Instead, use Service OS:

Service OS Password Reset Procedure

1. Reboot the switch (press Reset).
2. During boot, press 0 to enter Service OS.
3. Login: admin (no password).
4. Reset the primary admin password using:

   password reset

If a complete reset is still needed, execute:

erase zeroize

Part 4: Impact on VLANs, PoE, and Stacking

VLAN and IP Configuration

Factory reset erases all saved VLANs, static IPs, and security configurations. After reboot, the switch tries DHCP; if no DHCP server exists, configure a temporary static IP to regain management access.

PoE Devices

During reboot, all connected PoE devices lose power temporarily (IP phones, cameras, APs). Schedule resets to avoid business disruption.

VSF Stacking

Resetting a stack master may break the VSF relationship. For cleaning VSF manually:

Aruba-CX-6300# no vsf member 1

A reboot may be required; some old VSF info might persist and require additional CLI cleanup.

Part 5: Advanced – Batch Reset and ZTP

For MSPs or large deployments, you can automate factory resets using Aruba Central or Zero Touch Provisioning (ZTP) scripts. The erase zeroize command ensures devices are wiped clean before new configurations are pushed, avoiding manual reset of dozens of switches.

Part 6: Default Login After Reset

After a successful reset:

• Username: admin
• Password: blank (prompt to create new)
• IP: DHCP preferred; assign static IP if needed

This allows immediate reconnection and configuration.

Part 7: FAQ

What is the default username and password for Aruba CX 6100/6200/6300/6400?

Default login post-reset is admin with a blank password. You will be prompted to create a new password.

How do I reset an Aruba 6200 if I lost the admin password?

Access Service OS during boot, login as admin (no password), and use password reset. Avoid a full factory reset unless necessary.

Does factory reset affect stacking (VSF) or PoE devices?

Yes. Resetting the master can split the stack; connected PoE devices lose power during reboot. Use CLI commands like no vsf member 1 to clean VSF manually.

Can I use a physical button for factory reset on Aruba CX?

No. Unlike older models, the CX series has no hardware factory reset button. Reset only reboots the device.

What if the CLI or reset fails due to hardware issues?

Aging switches can fail in boot loops or flash corruption. In such cases, replacing the switch may be faster than repair. Check Router-switch for in-stock new or certified pre-owned units.

Part 8: Considerations for Upgrades and Replacement

If you encounter persistent configuration issues, aging hardware, or urgent deployment needs, replacement may be the optimal solution. For quick access to new or certified pre-owned Aruba CX 6000 Series switches, visit Router-switch.com to minimize downtime and meet tight deadlines.
