Removing the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C, or 8205-E6D system backplane

Learn how to remove the system backplane from a server to replace a failing part or as part of another service procedure.

1. Access the Advanced System Management Interface (ASMI).

   The ASMI is the interface to the service processor that is required to perform general and administrator-level service tasks, such as reading service processor error logs, reading vital product data, setting up the service processor, and controlling the system power. The ASMI might also be referred to as the service processor menus. To access the ASMI, see Accessing the Advanced System Management Interface. After you have accessed the ASMI, continue with the next step.

2. Check and record the System Enclosure Type and Feature Code.

   The enclosure serial number is a seven-digit number that is printed on a bar-coded label on the system unit.

   Note: The feature code number for the 8202-E4B, 8202-E4C, 8202-E4D, 8205-E6B, 8205-E6C, or 8205-E6D is 78AA-001.
