# Resetting the Product Password for Linear

# Performing a Factory Reset on the LA-5291, LA-5300, or UpMAX ISC via SSH

## Overview

This article describes how to perform a factory reset on the following Linear Acoustic products using an SSH connection:

- LA-5291
- LA-5300
- UpMAX ISC

The factory reset is initiated by running a reset script from the product's Linux command line.

> **Warning:** A factory reset restores the unit to its default configuration. Back up any required settings before proceeding.

## Prerequisites

Before you begin, ensure you have:

- Network connectivity to the product.
- The product's IP address.
- A Windows PC with **Tera Term** installed.
- Administrative access to the device.

## Connect to the Product Using SSH

1. Open **Tera Term**.
2. Select **TCP/IP**.
3. Configure the connection using the following settings:

| Setting | Value |
| --- | --- |
| **Host** | IP address of the LA-5291, LA-5300, or UpMAX ISC |
| **Service** | SSH |
| **TCP Port** | 22 |
| **SSH Version** | SSH2 |
| **IP Version** | Auto |
4. Select **OK**.
5. After a few seconds, a security confirmation window will appear. Select **Continue**.
6. When the **SSH Authorization** window opens, enter the following credentials:

| Field | Value |
| --- | --- |
| **Username** | `user` |
| **Password** | *(Leave blank)* |
7. Select **OK** to open the terminal session.

## Perform the Factory Reset

At the command prompt, enter the following commands:

```text
su
cd /usr/arc
./factory_reset.sh
```

> **Note:** There is a space between `cd` and `/usr/arc`.

## What to Expect

After the reset script is executed:

- The front panel display will go blank.
- The unit will begin the factory reset process.
- Once the reset is complete, the front panel display will return to normal.
- The web user interface should automatically reconnect after the device finishes restarting.

## Verification

After the unit has restarted:

- Verify that the front panel display has returned to normal.
- Connect to the web interface.
- Confirm that the device has been restored to its factory default configuration.
- Reconfigure the device or restore a saved configuration if required.

## Troubleshooting

If the reset does not complete successfully:

- Verify that the SSH connection was established using the correct IP address.
- Confirm you entered the commands exactly as shown.
- Ensure there is a space between `cd` and `/usr/arc`.
- Allow several minutes for the reset process to complete before attempting to reconnect.
- If the unit does not recover after the reset, contact Telos Alliance Technical Support for further assistance.
