Chapter 2: Installation

Watch Dog Enable/Disable

JWD controls the Watch Dog function. Watch Dog is a system monitor that can reboot the system when a software application hangs. Pins 1-2 will cause WD to reset the system if an applica- tion has frozen. Pins 2-3 will generate

anon-maskable interrupt signal for the application that is hung up. See the table on the right for jumper settings. Watch Dog must also be enabled in BIOS (setting located in the Power Menu).

Note: When enabled, the user needs to write their own application software in order to disable the Watch Dog tim- er.

PCI-X Slot Speed

Jumpers JPX1A and JPX2A can be used to change the speed of the PCI-X slot #1. Note that any JPX2A setting overrides all JPX1A settings. (To use a JPX1A setting, JPX2A should be left "open".) See the table on the right for jumper settings.

SAS RAID Select

JPS1 allows you to select between SR RAID, which is the default and enables SAS RAID, or IT RAID, which treats SAS drives as non-RAID drives and requires a firmware flash. See the table on the right for jumper set- tings and the following page for the IT firmware flash procedure.
