Configuring System Board Jumpers; Before You Begin - NEC EXPRESS5800 LC1400 series User Manual

Configuring System Board Jumpers

Before You Begin

Only a qualified technical person should perform the procedures in this section.
Electrostatic discharge (ESD) can damage the
system board. Modify the system board only at an
ESD workstation. Otherwise, wear an antistatic
wrist strap attached to chassis ground.
The system board jumpers enable you to set specific operating parameters for
your system. A jumper is a small plastic-encased conductor (shorting plug) that
slips over two jumper pins.
The "System board Jumpers" illustration shows the location of the system board
jumpers. The "System Board Jumper Configurations" table lists the system
board jumpers and their factory default settings.
