In-Band Automated Boot Recovery Method; Out-Of-Band Method; Automated Boot Recovery (Abr); Nx-Boot Failure - Lenovo x3550 M5 Installation And Service Manual

Step 21. Restart the server. The system begins the power-on self-test (POST).
Step 22. If these recovery efforts fail, contact your Lenovo service representative for support.

In-band automated boot recovery method

Use this information to recover the server firmware and restore the server operation to the primary bank.
Note: Use this method if the BOARD LED is lit and there is a log entry or Booting Backup Image is displayed
on the firmware splash screen; otherwise, use the in-band manual recovery method.
Step 1. Boot the server to an operating system that is supported by the firmware update package that
you downloaded.
Step 2. Perform the firmware update by following the instructions that are in the firmware update package
readme file.
Step 3. Restart the server.
Step 4. At the firmware splash screen, press F3 when prompted to restore to the primary bank. The
server boots from the primary bank.

Out-of-band method

Use this information to recover the server firmware and restore the server operation to the primary bank.
See the IMM2.1 documentation (Integrated Management Module II User's Guide) at
www.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5089484&brandind=5000008.

Automated boot recovery (ABR)

While the server is starting, if the integrated management module II detects problems with the server
firmware in the primary bank, the server automatically switches to the backup firmware bank and gives you
the opportunity to recover the firmware in the primary bank.
For instructions for recovering the UEFI firmware, see "Recovering the server firmware (UEFI update failure)"
on page 92. After you have recovered the firmware in the primary bank, complete the following steps:
Step 1. Restart the server.
When the prompt Press F3 to restore to primary is displayed, press F3 to start the server from
Step 2.
the primary bank.

Nx-boot failure

Configuration changes, such as added devices or adapter firmware updates, and firmware or application
code problems can cause the server to fail POST (the power-on self-test).
If this occurs, the server responds in either of the following ways:
• The server restarts automatically and attempts POST again.
• The server stops responding, and you must manually restart the server for the server to attempt POST
again.
After a specified number of consecutive attempts (automatic or manual), the Nx-boot failure feature causes
the server to revert to the default UEFI configuration and start the Setup utility so that you can make the
necessary corrections to the configuration and restart the server. If the server is unable to successfully
complete POST with the default configuration, there might be a problem with the system board.
