Replace the cover and reinstall the blade server in the BladeCenter unit, making sure that the blade server controls all relevant components and restart the blade server. 8. If the system starts up and boots to the operating-system prompt, see "Recovering the TEMP image from the PERM image." If the system does not boot to the operating-system prompt, replace the system-board assembly. Contact a service support representative for assistance. Note: If the blade server does not restart, you must replace the system-board assembly. Contact a service support representative for assistance. Recovering the TEMP image from the PERM image To recover the TEMP image from the PERM image, you must perform the reject function. The reject function copies the PERM image into the TEMP image. To perform the reject function, complete the following steps: 1. If you have not started the system from the TEMP image, do so now. For additional information, see "Starting the TEMP image" on page 48. 2. If you have not installed the ppc64 Linux utilities, perform the installation now.

Shut down the blade server using the operating system. 5. If you have not moved jumper J14 as described in "Starting the TEMP image" on page 48, restart the system. 6. If you moved jumper J14, complete the following steps: a. Turn off the blade server. b. Remove the blade server (see "Removing the blade server from the BladeCenter unit" on page 73). Chapter 7.
