Lost ILO 100c Password

If anyone has lost the 100c ILO password there is a great thread here to help:


Since it's set to read only I douldn't add the information on how to re-enable the admin account if you accidentally disable it... Not that I would do something silly like that.


I hope this saves someone from countless hours of misery that I had to go through.


Lights-out 100 does have an option to disable to Admin account in the web interface for the version 2.14 firmware or later. If that box was accidently checked, the admin account will not work.

To enable the admin account and resolve this issue, perform the following steps:

1.      Create a DOS bootable disk (floppy or USB key)

2.      Download the IPMItool from ( Click here to download the IPMItool )

3.      Copy the IPMItool.exe to the bootable disk

4.      Boot the server using the bootable disk

5.      Run "ipmitool.exe 20 18 47 03 01 61 64 6d 69 6e 00 00 00 00 00 00 00 00 00 00 00"

The following information applies to the hex code for the ipmitool:

"20 18" is the SetFN/LUN numbers (the ILIM address and type). 
"47 03" is the command string.
"02" means "set password"
"01" means "enable user"

The ASCII string for the password "admin" is "61 64 6d 69 6e 00 00 00 00 00 00 00 00 00 00 00"

Now the admin account should be enabled.


So instead of using 02 in the 5th set use 01 and this will enable the admin account.
