Checking jumper settings
The following procedure explains how to locate and, if necessary,
change jumper settings when you upgrade your processor. See this
section to also view factory jumper settings.
If a jumper change is required, lift the plastic block from the jumper
pins with needle-nose pliers and place the block on the appropriate
pins.
!
CAUTION
Jumpers are set correctly at the factory for your configuration.
If your system requires a jumper change, change only the
setting for that condition. Otherwise, keep the settings at
their factory settings.
!
WARNING
The system power must be off before changing a jumper
setting.
1.
Power off and unplug the system and any attached devices.
2.
Remove the system unit cover (see “Taking off the cover”
earlier in this guide).
