HPE Aruba Switch Factory Reset Guide: Step-by-Step CLI & GUI Instructions

Selene Gong

Are your HPE Aruba switches misbehaving, stuck in misconfigurations, or locked due to forgotten admin passwords?
Network administrators often face situations where a clean slate is the fastest way to restore stability. Performing a factory reset erases all configurations and returns the switch to its original state—crucial for troubleshooting, redeployment, or security. This guide walks you through step-by-step methods for safely resetting your Aruba switches using both CLI and GUI, covering AOS-CX, AOS-Switch, and Comware-based OfficeConnect devices.

Part 1: Why and When to Factory Reset Your Aruba Switch

Performing a factory reset is a drastic step, as it erases all configurations and data on the device. However, it's essential in these scenarios:

Troubleshooting Unresolvable Issues: Complex configurations may become corrupted or cause persistent problems. A reset restores a known good state.
Forgotten Administrative Passwords: When login credentials are lost, a factory reset often provides the only way to regain access.
Device Redeployment or Resale: Before moving a switch to a new network or selling it, a reset ensures all previous configurations and sensitive data are wiped.
Starting Fresh: Reconfiguring from scratch is often faster after a factory reset.

Part 2: Step-by-Step Factory Reset Guide for HPE Aruba Switches (CLI & GUI)

The procedure varies depending on switch series: AOS-CX, AOS-Switch, or Comware-based OfficeConnect. Note that many Aruba switches require a console connection for a full reset; the physical reset button often only reboots the device.

Method A: AOS-CX Switches (6100, 6200, 6300, 6400 Series)

Via CLI (with login credentials):

Connect to the console port via serial cable.
Log in with administrator credentials.
Execute:

erase all zeroize

This erases management files (except software images) and restores factory defaults.

Via Service OS (password recovery):

Reboot the switch and monitor the console output.
Enter Service OS (Option 0 or 1).
Execute:

erase zeroize

Switch resets to factory defaults.

Method B: AOS-Switch Devices (2530, 2540, 2920, 2930F/M, 3010M, 5400R)

Connect via USB or USB-serial cable.
Open serial console (9600 baud, 8n1).
Power cycle the switch.
Press 0 at "Boot Profiles:" to enter monitor console.
Execute:

erase-all

Confirm with y. Switch reboots with factory settings.

Method C: Comware-based Switches (OfficeConnect 1950, HP Series A 5900)

Via CLI:

Connect via console or Telnet.
Execute:

initialize

reset saved-configuration

If necessary, delete startup configuration manually:

display startup
delete startup.cfg

Reboot and skip saving current configuration.

Password Recovery / Bypass:

Press Ctrl+B during startup or enter menu option 4.
Use boot menu options to bypass authentication, then execute initialize.

Method D: Via Web GUI (if accessible)

Optional: press and hold reset button while powering on (10–15s).
Connect a computer directly to the switch.
Open browser to default IP (e.g., 192.168.1.1).
Log in with default credentials (e.g., admin/admin).
Perform factory reset via web interface.
Reconfigure as needed.

Part 3: Precautions, Backup, and Security Tips Before Resetting

Backup Configuration: Always save current settings before resetting.
Understand Data Loss: All VLANs, routing tables, and local accounts will be erased.
Physical Access: Password recovery usually requires direct access.
SSH/SSL Keys: CLI commands or reset buttons may not clear keys—delete manually if needed.
Model Specificity: Procedures differ across AOS-CX, AOS-Switch, and Comware models.
Change Default Credentials Immediately: Protect your switch after reset.

Part 4: FAQ – How to Factory Reset Your HPE Aruba Switch

Q1: How do you factory reset an Aruba switch?
Method depends on model and login access. Use erase all zeroize (AOS-CX), erase-all (AOS-Switch), or initialize / reset saved-configuration (Comware). GUI option may exist if web access is available.
Q2: How to do a full factory reset on Switch?
Full reset wipes all user configurations. Use CLI commands as above and manually delete SSH/SSL keys if needed.
Q3: How to factory reset Aruba 2920 switch?
AOS-Switch device: connect via console, power cycle, press '0' at "Boot Profiles:", then execute erase-all.
Q4: How to reset Aruba switch through CLI?
AOS-CX: erase all zeroize or erase zeroize from boot menu.
AOS-Switch: monitor ROM → erase-all.
Comware: initialize or reset saved-configuration, delete startup.cfg if needed.
