Here is a problem that you can see when replacing or installing new DIMMs in UCS Blades.
\nAlthough the blade will boot but the newly installed DIMMs might show as disabled with invalid FRU error:
\nError codes F0844 and F0502 are logged:
\n\"\"<\/a><\/p>\n

When you check inventory of the blade and go into Memoery you’ll see that Capacity<\/strong> and Clock<\/strong> are Unspecified<\/strong>.<\/p>\n

SSH into UCSM IP.

To try to fix the issue here the first thing you need to do in this case is Update Capability Catalog<\/strong> of UCSM. It could be that the newly installed memory is too new for UCSM to recognize.
\nHere is a post How to Update Capability Catalog<\/strong><\/a>. After updating the Capability Catalog\u00a0<\/strong>decommission and recommission\u00a0the blade or you can reseat blade or reset the slot where the blade is.
\nIf updating Capability Catalog<\/strong> does not help then it could be that you are hitting Cisco bug \u00a0CSCtu16549<\/a>.\u00a0<\/strong>According to bug details upgrading to UCS firmware 2.0(4a) or higher should fix the problem.<\/p>\n","protected":false},"excerpt":{"rendered":"
