---

## Goal

The goal of the steps below is to configure the switch so it will be able to upload **100G** to your server using the **SFP28 interface**.

## Steps Before Using the Switch

### Step 1: Connect the Fiber Optic Cable

- Connect the fiber optic cable to the **server** and to **port 25 or 26** in your switch.

### Step 2: Connect a Laptop for Configuration

- Use an **ethernet cable** to connect your laptop directly to the switch.

- The switch has a port marked **MGT (management)**. Connect the cable there and to your laptop.

- Once configuration is done, this cable can be disconnected.

### Step 3: Set Laptop IP Address

- By default, the switch uses IP **192.168.1.1**.

- Set your laptop LAN IP to the same range (e.g., **192.168.1.10**).

### Step 4: Access the Web Management Interface

- Open a browser and navigate to **192.168.1.1**.

- You should see the **web-based management system** of the switch.

### Step 5: Login to Web Interface

- Use the following credentials:

  - **User:** admin

  - **Password:** admin

## Switch Configuration via Terminal

### Step 6: Open a Terminal

- On the **server**: open a terminal.

- On your **laptop**: open **PuTTY** (or another SSH client).

- Connect to the switch:

  ```bash

  ssh admin@192.168.1.1

  ```

- Password: **admin**

### Step 7: Identify the 100G Interfaces

- The switch has two **100G interfaces**: port **25** and port **26**.

### Step 8: Configure Ports via SSH

Run the following commands:

```bash

configure terminal

interface eth-0-25

shutdown

no shutdown

speed 100g

duplex full 

fec rs

exit

interface eth-0-26

shutdown

no shutdown

speed 100g

duplex full 

fec rs

exit

write memory

reload

```

- Press **Enter** to confirm the reboot.

## Verification

- After reboot, login again to the **web interface**.

- Ports should show a **color change**, indicating successful connection.
