Hi,
I've recently bought a PRIMERGY RX300 S4 server. I've cleaned it and turned it on, and went into BIOS without any problem. Then I changed CMOS battery and server does not boot to BIOS any longer. This server has aftermarket memory installed (FB-DIMM, 4GB, 667MHz, made by Kingston) and only 3 fans instead of 4. Additionally when powered on it sits on Fujitsu logo without any text (no option to go to BIOS) and shuts down approx. 5 minutes after powering it on. When it is started while I am holding ID button it sits on Fujitsu logo as well. Is it a fan problem or it's something else?
