dl360-g7 password reset

Hi, I have one Proliant DL360 G7 Server. When I tried to enter the RAID configuration screen pressing F8 it asks for administrator password. But nobody knows it. I checked the service manual to reset it.The manual says to change the position of one DIMM switch (system maintenance switch, s6 ) to ON  position. But there is not a single switch in the board. In the place where the manual says the NVRAM Switch is located , I could not find a switch, but the location looks like , a position for DIMM switch but void of it.  

Please let me know how to reset the password  in dl360 g7 that does not have a  "system maintenance switch"

Thanks in advance.
