Note: Place all removed components that will be reinstalled later in this procedure, on an
electrostatic discharge (ESD) mat.
14. Label and disconnect the external cables that are connected to the system you are servicing.

Removing the expanded function system backplane from the 8247-42L,
8286-41A, or 8286-42A
Learn how to remove the expanded function system backplane from a server to replace a failing part or
as part of another service procedure.
To complete this procedure, you must have prepared the system to remove and replace the expanded
function system backplane. For instructions, see "Preparing the system to remove and replace the
expanded function system backplane" on page 58.
Complete the following steps to remove the expanded function system backplane:
1. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip is
connected to an unpainted metal surface. If not, do so now.
2. Remove the hinged air baffle. For instructions, see "Opening the air baffle on an 8247-42L, 8286-41A,
or 8286-42A system" on page 144 and "Removing the air baffle from an 8247-42L, 8286-41A, or
8286-42A system" on page 146.
