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.

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).
