Notes:
1. If no jumper is present, the server responds as if the pins are set to 1 and 2.
2. Changing the position of the boot block jumper from pins 1 and 2 to pins 2 and 3 before
the server is turned on alters which flash ROM page is loaded. Do not change the
jumper pin position after the server is turned on. This can cause an unpredictable
problem.
then, disconnect all power cords and external cables. Review the information in
vii, "Installation guidelines" on page 22, "Handling static-sensitive devices" on
