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.
