the password check (see “Clearing CMOS memory”).
Clearing CMOS memory
The CMOS recovery jumper is used to clear CMOS memory in the event you lose
your user or supervisor password. This jumper is also used to recover from a BIOS
failure. See “Recovering from a POST/BIOS update failure” on page 21.
Attention: Do not change settings or move jumpers on any system-board switch
or jumper blocks that are not shown in this book.
Complete the following steps to set the CMOS recovery jumper and erase a
forgotten password:
1. Review the “Safety information” on page 101 and “Handling static-sensitive
devices” on page 25.
2. Turn off the server and all attached devices.
3. Disconnect all power cords and external cables.
4. Remove the cover (see “Removing the cover and bezel” on page 27).
5. Locate the CMOS recovery jumper (JBAT1) on the system board, removing any
adapters that impede access to the jumper. The following illustration shows the
location of the jumper on the system board.

6. Change the position of the jumper on JBAT1 to bypass the password check.
