List, I have a P91 Poweredge 2900 thats not booting up, i am getting a BSOD once i pass the Win 2003 splash screen. I observed that the redundant power supply does not have a green light come up on the back of the AW near the power supply unit, and the message shown in status display also reflects the same. Is it absolutely necessary that a redundant power supply is needed for this class of AW. Is there an option where you can turn off the necessity for redundant power supply. Appreciate your help guys Venu _______________________________________________________________________ This mailing list is neither sponsored nor endorsed by Invensys Process Systems (formerly The Foxboro Company).
