How to Log in to VSOL OLT

VSOL OLT supports multiple login methods, allowing flexible access for both initial deployment and daily network management.

Method 1: Web Login (Recommended)

Web login is the most intuitive method, especially for initial configuration.

1. Connect your PC to the OLT management port
2. Set your PC IP address in the same subnet (e.g., 192.168.8.x)
3. Open a browser and enter: https://192.168.8.100

4. Enter your username and password to access the system (Default username and password: admin/Xpon@Olt9417#)

Notes:

• Default Web access uses HTTPS (port 443)
• Ensure browser security settings do not block access

Method 2: Console Login (CLI Access)

Console access is typically used for first-time setup or troubleshooting when remote access is unavailable.

1. Connect the OLT to your PC using a console cable
2. Open a terminal tool (such as PuTTY or SecureCRT)
3. Configure serial parameters (commonly 9600 baud rate)
4. Log in using your credentials (Default: admin/)

Method 3: Remote Login (Telnet/SSH)

For remote management, VSOL OLT supports Telnet and SSH access.

• Ensure the OLT has a reachable IP address
• Enable Telnet or SSH if required
• Access via:

telnet <OLT-IP> or ssh <OLT-IP>

Note: SSH is recommended over Telnet for better security.

Common Login Issues and Troubleshooting

If you cannot log in to your VSOL OLT, check the following:

• Use HTTPS instead of HTTP
• Verify the correct management IP address
• Confirm the Web management port (default 443)
• Ensure your PC and OLT are in the same subnet
• Check access control settings via CLI if configured

What is VSOL OLT Default Password?

The default login credential for VSOL OLT is as follows:

Username: admin

Default Password: Xpon@Olt9417#

Important Notes

• Default credentials may vary depending on device model and firmware version
• Some devices may require password initialization on first login

What to Do If You Forgot the OLT Password

3. Perform a factory reset if necessary
4. Contact VSOL technical support for assistance

VSOL mainly provides product customization and volume purchase services to resellers and operators.

So how do I become a partner reseller? Product requirements can be contacted and communicated in the following ways:

1. If you are viewing a product, you can leave a message via the ‘Enquiry’ button on the product detail page.
2. Click on the Contact Us page and send a message through the message system and email address on the page. After receiving the message, we will contact you within 24 hours.

VSOL does not have an e-commerce channel for the time being, and therefore cannot offer products directly to individual buyers.

But we offer a better solution. If you are an individual buyer and need a small amount of product for home or office use, then you can contact your local distributor customer instead of purchasing the product through VSOL.

The local distributor can provide you with equivalent quality products and service support without incurring additional shipping costs.

Need to know about local dealer customers can be accessed in two ways:

1. The Partners page of the website.

2. Submit a message on the contact page or contact customer service online.
