Note –
(1) Memory mirroring requires twice the amount of memory domain used
for operation. If the PSB is a Quad-XSB type in M8000/M9000 servers, memory
mirroring cannot be used. In M4000/M5000 servers, memory mirroring can be used
regardless of whether the system board is a Uni-XSB or Quad-XSB.
Note –
(2) The add/delete/replace operation
s
are done by field engineers (FEs). If a
command is performed, the maintenance guidance is displayed. FEs will use the
device check, select, add, and delete operations in the guidance window. For
information about how to handle and operate these devices, see the
Service Manual
for your server and any manual written for FEs.
