IBM xSeries 342: User’s Reference
The following table describes each switch.
Switch number Description
1 through 4 Reserved.
5 Clock frequency selection.
Switch 5 should always be set to Off to optimize system performance.
Setting switch 5 to On greatly reduces system performance.
6 Password override.
Change the setting of the password override switch (switch 6 on switch
block 1 on the system board) to the opposite side of the switch. This
allows one opportunity to enter the Setup Utility to change or delete the
power-on password.
7 Reserved. The default setting is Off.
8 Power-on override.
When On, overrides the power-on switch and forces power-on mode. The
system will always start without the use of the power-on switch. The
default setting is Off (disabled).
Note: When the power-on switch is set to the On position, you cannot
power down from the front panel.
