Switch number
Default position Description
1 Off TPM/TCM physical presence.
2 Off Reserved.
3 Off Reserved.
4 Off Clear CMOS memory. When this switch is toggled to ON, it clears
the data in CMOS memory, which clears the power-on password.
5 Off Force UEFI recovery. Changing the position of the switch to ON will
force the system to boot from the recovery UEFI image.
6 Off Force XCC backup bank. Changing the position of the switch to ON
will force the system to boot from the backup XCC bank.
7 Off Power-on password override. Changing the position of this switch
bypasses the power-on password check the next time the server is
turned on and starts the Lenovo XClarity Provisioning Manager Lite
so that you can change or delete the power-on password. You do
not have to move the switch back to the default position after the
power-on password is overridden.
Changing the position of this switch does not affect the
administrator password check if an administrator password is set.
8 Off Reserved
Important:
1. Before you change any switch settings or move any jumpers, turn off the server; then, disconnect all
power cords and external cables. Review the information in

, “Installation Guidelines” on page 89, “Handling static-sensitive
devices” on page 91, and “Power off the server (disconnect input power)” on page 65.
