Memory Monitoring - Hitachi HF-W7500 40 Manual

2.5 Memory Monitoring

Memory with Error Checking and Correcting (ECC) is installed in this equipment. A single
bit error in the memory can be automatically corrected without causing any problems to the
operation of the equipment. On the other hand, if the frequency of memory error correction is
high, that is considered to be caused by memory failure, and we recommend replacing the
memory modules from the viewpoint of preventive maintenance.
The memory monitoring function notifies in the following methods when the frequency of
memory error correction is high.
(1) Event notification
(2) Popup notification
(3) Remote notification
(4) The GetMemStatus function in the RAS library
For details about (1) to (3), see "CHAPTER 4 CHECKING THE HARDWARE STATUS".
For details about (4), see "6.1.7 Get function for the memory condition (GetMemStatus)".
NOTE
For information about how to replace a memory module, refer to "HF-W7500
Model 40 INSTRUCTION MANUAL (manual number WIN-62-0065)".
