Configuring the Remote Management (BMC)

The Baseboard Management Controller (BMC) is a powerful, independent processor inside your server that allows for complete remote control. This is often referred to as "out-of-band" management. Configuring it is the most critical step to prepare your server for production use. This chapter will guide you through accessing the BMC's web interface for the first time and performing the essential initial setup.

Accessing the BMC web interface

To get started, you'll need to find the server's management IP address and use it to log in.

1. Connect the management port. Locate the dedicated network port labeled MGMT at the rear of the server and connect it to your management network.

   
2. Find the IP address. By default, the server is configured to get an IP address automatically from a DHCP server on your management network. You can find this IP address in two common ways:

   • Check your DHCP server: Look at the active leases on your DHCP server to find the IP address assigned to the BMC's MAC address.

   • During server boot: Watch the screen during the Power-On Self-Test (POST) sequence. The BMC IP address is often displayed on the screen.

     
3. Open a web browser. On a computer connected to the same management network, open a web browser and enter the IP address you just found.

4. Log in to the interface. You should see the BMC login page. Use the default credentials to log in:

   • Username: root

   • Password: 0penBmc (The first character is a zero)

     

Performing initial setup

After your first successful login, you must perform two critical security and networking tasks.

Step 1: Change the default password

1. Navigate to the User Management or Settings section of the web interface.

2. Select the root user account.

3. Follow the prompts to create a new, strong password.

Step 2: Configure a static IP address

While DHCP is useful for the initial connection, a server's management interface should have a permanent, predictable IP address.

1. Navigate to the Network Settings section.

2. Change the configuration from DHCP to Static.

3. Enter the static IP address, subnet mask, and default gateway provided by your network administrator.

4. Save the changes. The BMC may restart its network service, and you will need to reconnect using the new static IP address. [Image, NEW: A screenshot of the BMC network settings page, with the fields for static IP, subnet, and gateway clearly highlighted.]
