features, refer to the User's Guide.
Also, refer to the User's Guide for the addition of a Memory Board or DIMM to the Server.
In the redundant memory configuration (memory mirroring or memory RAID configuration), the
Memory Board can be removed for DIMM replacement while the power of the Server remains ON
(hot-pluggable).
The following describes how to replace a Memory Board or DIMM in the normal or hot-pluggable
configuration:
In the redundant memory configuration, the Redundancy lamp on the Memory Board goes on
green when the power of the Server is turned on.
The figure shows the Server mounted on the 140Rd-4 chassis. The Server on the 140He chassis is
different only in that it is mounted longitudinally. The replacement procedure is the same for both
servers, except when specified otherwise.
[Replacement in normal configuration]
1. Make sure that the power of the Server is set to OFF and disconnect the power cables
from all the power units.
2. Release the lock on the front bezel by using the security key to remove the front bezel.
3. Remove the memory slot cover on the front of the Server (by removing the two captive
