LAN Enable/Disable
Change the setting of jumper JPL1
to enable or disable the onboard
Ethernet (RJ45) ports LAN1 and
LAN2. See the table on the right for
jumper settings. The default setting
is enabled
Watch Dog Enable/Disable
JWD1 controls the Watch Dog function.
Watch Dog is a system monitor that
can reboot the system when a software
application is “hung up”. Pins 1-2 will
cause Watch Dog to reset the system if
an application is hung up. Pins 2-3 will
generate a non-maskable interrupt sig-
nal for the application that is hung up.
See the table on the right for jumper
settings. Watch Dog must also be en-
abled in BIOS.
Note: When enabled, the user needs
to write their own application software
to disable the Watch Dog Timer.

3rd Power Supply Fail Detect
Enable/Disable
The system can notify you in the event
of a power supply failure. This feature
assumes that three power supply units
are installed in the chassis with one
acting as a backup. If you only have
one or two power supply units installed,
you should disable this (the default set-
ting) with JP13 to prevent false alarms.
See the table on the right for jumper
settings.
