Replacing Memory Bar
This section describes how to replace a memory bar. See Figure 47.
Figure 47 Memory bar maintenance flow
Memory bars are main board components that you can expand or upgrade as
needed. Generally, you need to do that in the following situations:
■
More memory is required for the updated application program, maintaining a
large routing table, or processing tasks that consume large memory.
■
The existing memory bar is damaged.
c
CAUTION:
■
Hold the memory bar by its edge and avoid touching the components on its
surface. An improper operation might result in damage.
