# Baremetal Installation

### Requirements

Minimal server requirements:

* 64-bit server
* USB key for installation (or Optical disk drive)
* One Ethernet interface for management
* One or more Ethernet interfaces for SBC processing (LAN/WAN). Must be in the [List of supported NICs](/initial-installation/1.-instructions-by-platform/baremetal-installation/list-of-supported-network-interface-cards.md)
* Two Ethernet interfaces, if a 1+1 configuration is required
* Console access through serial port or keyboard/monitor ports or other (i.e. Dell iDrac)
* Support for the "Legacy BIOS mode with MBR partition" or UEFI (UEFI support new with version 3.1.117)
* BIOS setup for maximum performance (no dynamic CPU throttling)

In most cases, a standard configuration will provide sufficient performance. To get maximum performance from a system, please open a case on [TelcoBridges support portal](https://telcobridges.odoo.com/).

### Getting the ISO

Please go to our [Dashboard](http://dashboard.telcobridges.com/) to get a copy of the latest SBC ISO.

### Installing the ISO

The installation process will reformat the server's disks and install all the necessary software.

#### Prepare an ISO onto a bootable USB flash drive or a DVD

Use a software application to burn the ISO image to a USB flash drive. On Windows, [Rufus ](https://rufus.ie/en/)is known to work with the ProSBC ISO, however, any similar application should work.\
When using Rufus, make sure you have these settings:

* Partition scheme: MBR
* Target system: BIOS or UEFI
* Volume label (keep default): "CENTOS 7 X8"
* File system: FAT32

Press START, then select:

* Write in ISO Image Mode (Recommended)

#### Physical installation steps

1. Identify which Ethernet networks you need and connect them to your server. Refer to Networking for more information. For ProSBC Transcoding and associated network setup, please also refer to [ProSBC:Transcoding and Network Setup](/configuration-details/configuration-by-use-case/transcoding-unit-configuration/baremetal-and-virtual-machine.md).
2. Burn the ISO onto a DVD or a USB flash drive
3. Get access to the console of the server. Usually, this is achieved by connecting a keyboard and screen to the server.
4. Insert the DVD in the optical drive of your server and boot from the DVD drive.
   * Alternatively, plug in your USB flash drive and boot from that drive.
5. The "Virtual Appliance Installer" menu should be displayed:<br>

<figure><img src="https://docs.telcobridges.com/w/images/thumb/5/59/ISO_install_prompt.jpg/600px-ISO_install_prompt.jpg" alt=""><figcaption></figcaption></figure>

1. Press the 'R' key followed by the 'ENTER' key to start the installation<br>

<figure><img src="https://docs.telcobridges.com/w/images/a/a1/ISO_installing.jpg" alt=""><figcaption></figcaption></figure>

1. Wait for the installation process to complete. When the installation is complete, the server will automatically reboot.
   * Important: Make sure to remove the DVD from the drive while the server is rebooting. If you get back to "Virtual Appliance Installer", just eject the CD or remove the USB flash drive and reboot again.
2. It may take a couple of minutes for the system to be brought up after the first reboot. Until the Web Portal is accessible, you must not reboot the newly created machine to allow the installation to complete properly.

#### Assigning IP address

By default, all detected network interfaces will have DHCP enabled. This means, the server might already have an IP address assigned, if the network has a DHCP server running. In this case, you can display and use it to access the web portal configuration panel.

1. Retrieve an IP address assigned by DHCP

```
 # ifconfig
```

If you want to assign a static IP address, or there is no DHCP on your network, you will need to configure it manually.

1. Use the [tbchangeip](/initial-installation/2.-initial-configuration/initial-setup/sbc-management-ip-configuration.md), shell command and answer the questions to change your Ethernet interface address:

```
 # tbchangeip
```

Note: tbchangeip command applies for management interface (mgmt) only. This command does not apply for control interface (ctrl) nor voip interfaces (voip).

\
Note: No changes must be done to the repositories on the systems, and no other software should be installed unless written consent from TelcoBridges.

#### Accessing the SBC web portal

1. Open a web browser to the IP of your server, on port 12358. Example if your server address is 192.168.178.30, the URL would be:\
   [http://192.168.178.30:12358](http://192.168.178.30:12358/)
2. The SBC Configuration Wizard is displayed<br>

From here, you can go to [Web Portal Initial Configuration Guide](/initial-installation/2.-initial-configuration.md) to continue the installation, and/or [optimize ](https://docs.telcobridges.com/w/index.php?title=TSBC-SW:Baremetal:Optimizations\&action=edit\&redlink=1)your server to get the maximum out of your server.
