Table 4. System board switch block 4, switches1-4
Switch
number Default value Switch description
1 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
Setup utility 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 259 for additional information about the power-on
password.
2 Off Power-on override. When this switch is toggled to On and then to Off, you force a
power-on which overrides the power-on and power-off button on the server and
they become nonfunctional.
3 Off Forced power permission overrides the IMM power-on checking process. (Trained
service technician only)
4 Off Reserved.
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 169, and “Handling
static-sensitive devices” on page 171.)
2. Any system-board switch or jumper blocks that are not shown in the illustrations
in this document are reserved.
