Hey guys so i have been having this major issue for the last few hours now. I have a system x 3550M2 server and i ran the UEFI and IMM firmware upgrades within windows server 2008 R2 x64. All upgrades went fine and i was told to reboot. I performed the reboot cleanly using the OS restart option. Upon restarting it showed the system initializing screen and it stayed there for a good hour. After that hour i figured it froze and so i powered down and power up again. Now i can not boot back up to even see the IBM splash screen or the OS... I have tried switching the Jumpers to go to the backup UEFI and backup IMM and no luck. I have also reset the CMOS power and i have pressed the reset button 3 times on the light path and no luck. There are no lights light on the light path to indicate anything is broken. The only thing i see on the light path is the number 0.5. Any ideas guys i am quite stumped with this problem.

Thanks a lot,

Dani Cela

don't forget unplugging from power - this is not a joke. unplug the machine from the outlets for at least 30s.

+1 for that! After administering bunch of xSeries servers for years I can tell you that many mysterious problems disappear after unplugging the machine from the outlet for a minute or so and plugging it back in. "Mysterious problems" including "hard server freezes" and "degraded performance". – Janne Pikkarainen Aug 1 '11 at 12:42

Pull the CMOS battery for 5 minutes, then replace the battery and try starting the system again.

If it still fails to boot, call IBM for hardware support (+1-800-IBM-SERV).
