Hi. After a Maintenance job (Dry air cleaning and visual check) , a DL380 Gen7 server can't boot. In the insight panel appears a Ram error (All leds in ambar). After so many test, the error seems be a no detectable RAM. The server only has 1 CPU in the #1 Slot and 2x2gb RAM in A-B slots. Until yesterday works fine. After the shutdown and maintenance, the error appears.
This's already done:
* Deep cleaning of DIMM slots and memory's pin (Dry pressed air, electronic contact cleaner, etc)
* Deep cleaning of whole motherboard, including full disassembling.
* Change ram for new modules in same configuration.
* Reset of NVRAM (in dipswitch 6 on maintenance switch)
* Check in ILO (Error: Memory configuration error)
* Only for test purposes, change to #2 Slot Proc and RAM. In this point, the server boot, display video and obviously, appears the PROC1 error and the system is halted (In insight panel and display).
My questions:
It's possible a damage ini the DIMM slots that make this fail?
May be due a missuse in the manteinance job?
It's possible change the configuration for use only a #2 Proc?
Please, I' really need repair this server and i' don't know what else to do
