Chapter 2 Powering On the Server Module, Configuring BIOS and Resetting BIOS, SP and CMOS 2-33
2.4 Resetting the BMC, BIOS, and CMOS
This section provides information about resetting the SP, BIOS, and CMOS
passwords. You can use the BIOS Setup Utility to reset the SP password. To access the
BIOS Setup Utility, you must setup the server with a keyboard, video, and mouse
(KVM). You can attach a KVM to the server or use a remote KVM (RKVM).
You need to use a hardware-based option to reset the BIOS password and clear the
CMOS password. This option requires that you remove the server module from the
chassis, access the motherboard, and use a jumper to short pins on jumper J42.
