Table 2. Switches 1 - 8

Switch		Switch
number	Default value	description
8	Off	Reserved.
7	Off	Reserved.
6	Off	Reserved.
5	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
		Configuration/Setup Utility program 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
		password is overridden.
		Changing the position of this switch does not affect the administrator password check
		if an administrator password is set.
		See “Passwords” on page 84 for additional information about the power-on password.
4	Off	Reserved.
3	Off	Reserved.
2	Off	Reserved.
1	Off	Clear CMOS. When this switch is toggled to On, it clears the CMOS data, which
		clears the power-on password.

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 “Safety” on page v, “Installation guidelines” on page 29, “Handling static-sensitive devices” on page 31, and “Turning off the server” on page 12.)

Attention: In a dc power environment, only trained service personnel other than Lenovo service technicians are authorized to connect or disconnect power to the dc power supply. See the documentation that comes with each dc power supply.

2.Any system-board switch or jumper blocks that are not shown in the illustrations in this document are reserved.
