Chapter 5: Subsystem Maintenance and Upgrading
Step 6.
Secure the controller module to the chassis
by
fastening the two (2) captive screws.
Step 7.
Re-attach all cables
that were removed. These include
the Fibre Channel host links, Ethernet cable to the
management port, and serial cables to the COM ports.
WARNING!
․
Unnecessary tampering with the controller module can
cause damage. Remove the controller ONLY when it is
absolutely necessary.
․
When you remove a controller module from the chassis, all
anti-static preventative measures should be strictly adhered
to. Failure to adhere to specified cautionary measures could
result in damage to the controller board.
5.3
Replacing a DIMM Module
The subsystem comes with a preinstalled 512MB 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.
5.3.1 DIMM
Module
Considerations
If the memory module on the controller module is going to be replaced,
the following concerns must be addressed when you purchase a
replacement module:
•
Purchasing considerations:
Contact your subsystem vendor for
a replacement or purchasing a DIMM module with larger capacity.
•
DDR RAM DIMM modules supported:
The controller supports a
DDR RAM DIMM module with memory capacities ranging from
512MB to 2GB. In a redundant-controller configuration, the DIMM
modules in partner controllers must be of the same size and
speed.
•
The physical size:
The controller only supports the DDR RAM
DIMM modules smaller than 30.5mm wide (1.2 inches).
•
Installation considerations:
When you remove the old DIMM
module, it is necessary to remove the controller from the chassis.
The controller board is more susceptible to damage than other
components and must be handled with extreme care.
