System-board layouts The following illustrations show the connectors, LEDs, and jumpers on the memory card, microprocessor board, PCI board, SAS backplane, and I/O board. The illustrations in this document might differ slightly from your hardware. I/O board internal connectors and jumpers The following illustration shows the internal connectors and jumpers on the I/O board. Table 2 describes the function of each three-pin jumper block. Table 2. I/O board jumper blocks Jumper name Description Force power on (J2) The default position is pins 1 and 2. Change the position of this jumper to pins 2 and 3 to force the server to startup when you connect the server to ac power. Power-on password (J9) The default position is pins 1 and 2. Change the position of this jumper to pins 2 and 3 to bypass the power-on password check. Boot recovery (J14) Wake on LAN® bypass (J15) Changing the position of this jumper does not affect the administrator password check if an administrator password is set. If the administrator password is lost, the operator information panel must be replaced. The default position is pins 1 and 2 (use the primary page during startup). Move the jumper to pins 2 and 3 to use the secondary page during startup. The default position is pins 1 and 2. Move the jumper to pins 2 and 3 to prevent a Wake on LAN packet from waking the system when the system is in the powered-off state. 8 IBM System x3850 Type 8864: Problem Determination and Service Guide
