Notes:
1. If no jumper is present, the server responds as default.
2. Changing the position of the boot block jumper from pins 1 and 2 to pins 2 and 3 for 5
seconds 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.
3. If a message is shown indicating that your Trusted Platform Module's (TPM) physical
presence is asserted, it is an indication that the system is vulnerable to potential security
risks. This occurs when the jumper setting of JP11 is at Pins 2 and 3. Switching the
jumper setting to Pins 1 and 2 of JP11 will deassert the Trusted Platform Module's
(TPM) physical presence.
then, disconnect all power cords and external cables. Review the information in
