Figure 26. Replacing the power supplies in the system

5. Reconnect the power cords to the power supplies.

For instructions, see “Connecting power cords to an 8335-GTC, 8335-GTG, 8335-GTH, 8335-GTW, or

6. If applicable, close the rack door at the rear of the system.
7. Start the system. For instructions, see “Starting the 8335-GTC, 8335-GTG, 8335-GTH, 8335-GTW, or

8335-GTX system ” on page 38.

8. If the BMC card was replaced continue to the next step, otherwise go to step “11” on page 37.
9. Configure the BMC IP address.

For instructions, see Configuring the BMC IP address (www.ibm.com/support/knowledgecenter/

POWER9/p9eih/p9eih_configuring_bmc_ip.htm).

10. Enter the network settings that you recorded earlier.

For instructions, see Network settings (www.ibm.com/support/knowledgecenter/POWER9/p9eih/

p9eih_openbmc_networksetting.htm).

11. Replace the front cover. For instructions, see “Installing the front cover on an 8335-GTC, 8335-GTG,

8335-GTH, 8335-GTW, or 8335-GTX system” on page 43.

12. If applicable, close the rack front door.
13. Verify the installed part.
