The detected memory size, in MB, is the first number following the error code. The expected memory size for the cluster is the second number following the error code. This problem might have occurred because a memory module has failed or because failing memory modules were exchanged and the wrong size modules were installed.
Check the memory size of another 2145 that is in the same cluster. For the 2145-4F2, exchange the memory modules in this 2145-4F2 for modules of the correct size. For the 2145-8F2, 2145-8F4, 2145-8G4 and 2145-8A4, if you have just replaced a memory module, check that the module that you have installed is the correct size, then go to the light path MAP to isolate any possible failed memory modules.
