Table 2. System board jumpers (continued)
Jumper number
J31
Notes:
1. If no jumper is present in JP1 or JP6, 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.
Important:
1. Before you change any switch settings or move any jumpers, turn off the server;
then, disconnect all power cords and external cables. Review the information in
v, "Installation guidelines" on page 26, "Handling static-sensitive devices" on
page 28, and "Turning off the server" on page 16.
2. Any system-board switch or jumper blocks that are not shown in the illustrations
in this document are reserved.
