Step 1 - Check Jumper Block Settings
Overview
The first step in configuring the P5000HX is checking the
jumper settings on the board.
What are jumpers?
Jumpers are small metal “bridges” that connect pins in a
jumper block on a CPU board. The position of a jumper
affects the board’s operational parameters.
Jumper blocks
The P5000HX contains:
•
five (5) three-pin jumper blocks (JP2, JP3, JP4,
JP5 and JP7), and
•
two 2) two-pin jumper blocks (JP6 and JP8).
Settings
Settings for these jumper block are provided in the
following tables.
JP2, JP3, JP5
Pin 2 jumpered to Pin 3
