description
8 Off Reserved.
7 Off Remote Supervisor Adapter II SlimLine BIST. When this switch is toggled to On, it
causes the Remote Supervisor Adapter II SlimLine to execute the Built In Self Test
(BIST).
6 Off Power-on override. When this switch is toggled to On, it forces the power on,
overriding the power-on button.
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 the User Guide on the ThinkServer Documentation DVD for additional
information about the power-on password.
4 Off Force BMC update. When this switch is toggled to On, it causes an update of BMC
firmware from the diskette drive.
3 Off Force BMC reset. When this switch is toggled to On, it forces the BMC to reset.
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.
Notes:
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 vii, “Installation guidelines” on page 53, and “Handling
static-sensitive devices” on page 55.)
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.
