Yes,  as EMC said, you can ignore this alert.  You normally get it when you have a CX4-120/240/480.  it is from the system polling for memory sticks or something that your model does not have.  I manage (2) Cx4-240's and they both give this alert in event monitor.   If it is actually sending you email alert,  you can edit the email home template and uncheck it  there is a primus article out there forit but dont know it off the top of my head.
I find the below warning alert in the 'CLARiiON' event viewer very often.  I have checked with EMC at the beginning stage, but they said to ignore this alert.  But i see this alert very often, please advise.  "SMBus read failed for device Local SPD DIMM3. Failure occured at 12C addr 0xA4 after 28800 unsuccessful attempts. Device error."
