Question We has bought two servers, which both use CSE-846TQ-R900B, K-revision. However, these chassis have different mounting rails, and the ones he received now don’t fit into his server rack, while the older ones are okay. The older ones are wider, while the newer ones look more „high-tech“, he says. Answer After check the version, if you used K3 version need use P/N: MCP-290-00014-00 P/N: MCP-290-00057-0N and P/N: MCP-290-00058-0N are for K4 version. Was this FAQ helpful?
