The following figure shows an example of the controller's management port location ( shown):
2. Open a browser and use the default IP address (169.254.128.101) to establish a connection to
the controller. The controller sends back a self-signed certificate. The browser informs you that
the connection is not secure.
3. Follow the browser's instructions to proceed and launch ThinkSystem System Manager.

If you are unable to establish a connection, verify that you are not receiving
network configuration from a DHCP server.
4. Set the storage system's password to login.
5. Use the network settings provided by your network administrator in the Configure Network
Settings wizard to configure controller A's network settings, and then select Finish.

Because you reset the IP address, System Manager loses connection to the
controller.
6. Disconnect your laptop from the storage system, and connect the management port on
controller A to your network.
7. Open a browser on a computer connected to your network, and enter controller A's newly
configured IP address.
If you lose the connection to controller A, you can connect an ethernet cable

to controller B to reestablish connection to controller A through controller B
(169.254.128.102).
8. Log in using the password you set previously.
The Configure Network Settings wizard will appear.
9. Use the network settings provided by your network administrator in the Configure Network
Settings wizard to configure controller B's network settings, and then select Finish.
