Hello Phizmo, Here is the EMC part#’s for a replacement SP. EMC part# 103-048-101c, 103-051-100E, 303-129-100B Please let us know if you have any other questions.
I have a CX4-120 that is not under warranty and it has a few issues. I had a previous error that a DIMM failed on SPS B. I replaced the the DIMM and that error went away. Along with the previous failed DIMM message there is a message that SP B is faulted 0x7403, Unisphere can no longer manage SP B 0x743a, and SPE Power B0 and B1 are faulted 0x7402. I tried connecting to the SP B ipaddress\setup to reboot the management for SP B but I can't connect nor can I ping the ip address of SP B. There are no amber lights on the back of the SAN. On the front the CPU Module B triangle light is blinking.  In Unisphere under the storage hardware view Enclosure SPE shows F, Enclosure SPE Power B0 and B1 show faulted, SP B shows removed while CPU module B and DIMMs B show present and Enclosure SPE SPS B shows removed. I also see this: SPAPeer Boot State:Failed. Illegal Configuration e.g SAN Enclosure is put into NAS. Recommendation: Reconfig SPBPeer Boot State:Invalid. Invalid boot fault information I have no warranty on this so if I have to replace a part I can do that. I am at a loss of what the issue is. Any suggestions would be gratefully appreciated.
