Hi Raphlou,   I can see that the SP is faulted here… , and you may have to go for a replacement .., you have mentioned that the LED blinking once every 4 seconds, meaning that the Boot sequence got stuck @ BIOS test , which means it a Hardware Failure…   Regards, Suman Pinnamaneni
Hello EMC specialists,  I would like to get your help on a big problem that I have met for the first time : I have a CX300 system which was fully operational. I have checked the logs, and I have seen a message that I have not kept, telling that the battery is failed. I have removed the storage processor and I have replaced the lithium battery, which was completely discharged : 1,2 V for a 3V battery. After battery replacement, I have verified the voltage on pins, and I have plugged again the storage processor, but now it is unreachable : At power up, the status LED stays on the phase : 1 flash for 4 seconds. No activity on drives 0 and 2 for SPA boot. There is no traffic at all on the serial management bus, and the SP stays not pingable. I have followed the ESD rules, and the SP was on an antistatic bag when I have changed the battery.  Could you tell me if I have forgotten a specific step, and could you tell me how to restart the system normally ?  Normally I should get : And this is that I have on SP B :  PhoenixBIOS 4.0 Release 6.0.Copyright 1985-2001 Phoenix Technologies Ltd.All Rights Reserved EMC Snapper Release 3.35 CPU =  Intel(R) Pentium(R) III CPU - S          800MHz256 MB System RAM Passed    Copyright (c) EMC Corporation , 2006Disk Array Subsystem ControllerModel: CX300DiagName: Extended POSTDiagRev: Rev. 02.57Build Date: Thu Jun 01 14:42:06 2006StartTime: 07/02/2012 10:39:49SaSerialNo: CF2BF044900033 ABabCabcDabcdeEFGabHabIabcJabKabLabMabNabOPQRInitializing back end FIBRE... ... ...
