Step 6. Re-attach all the cables that were removed. These include the
host link cables, Ethernet cable to the management port, and
serial cables to the COM ports.
5.3 DIMM Module Replacement
The subsystem comes with a preinstalled 512MB capacity or above DDR
RAM DIMM module on each controller. The controller supports memory
up to 2GB in size. If any of the memory modules have failed or a different
size DIMM module is preferred, the preinstalled module can be replaced.
Replacement and installation instructions are described fully below.
5.3.1 DIMM Module Considerations
If the memory module on the controller module is going to be replaced, the
following issues must be considered when purchasing a replacement
module:
•
Purchasing considerations: Contact your subsystem vendor for an
updated list of compatible DIMM modules.
IMPORTANT!
The DIMM modules that reside on partner controllers must be exactly
the same, of the SAME SIZE and SPEED.
•
DDR RAM DIMM modules supported: The controller supports a DDR
RAM DIMM module with memory capacities ranging from 512MB to
2GB.
•
The physical size: The controller only supports DDR RAM DIMM
modules those are smaller than 30.5mm wide (1.2 inches).
