# Accessing Device

There are 3 ways to access the Tmedia, Tsig or Tdev.

### Web Portal

The web portal is used to configure the line interfaces, signaling stacks, routes, and more.

It is also used to retrieve status about the system. See [Web Portal](/appendices/appendix-a-glossary/glossary-web-portal.md) for more information.

### SSH

The SSH connection is used to manage the device for operations, such as [changing the management IP address](/troubleshooting-and-support/troubleshooting-tips-and-actions/tbsigtrace-signaling-trace-capture-tool/accessing-device/tmg-change-management-ip-address.md), modifying the default password of the management interface, or for advanced troubleshooting.<br>

[Putty](http://www.putty.org/) is a common tool for accessing devices using SSH. With this tool, you need to enter the IP address of the management port and select the SSH connection type (default TCP port is 22). From any linux server, you can use the SSH command line option. Other tools are also available.

See 'Connecting to the Management Interface' of your [product installation guide](/appendices/appendix-b-product-datasheets.md) for more information.

### Serial Connection

The serial connection is used when the SSH connection is unavailable, or for advanced troubleshooting operations.<br>

[Putty](http://www.putty.org/) can be used to access the serial port using standard parameters: 9600-8-N-1.

See 'Connecting to the Serial Port' of your [product installation guide](/appendices/appendix-b-product-datasheets.md) for more information.
