I/O Board Jumpers Jumper Name 6 J17 Power on password override Description Changing the position of this jumper bypasses the power-on password check. You do not need to move the jumper back to the default position after the password is overridden. To do this: 1. Shut down and power-off the system. 2. Move jumper J17; then, power-on the system. POST will clear the password. Note Changing the position of this jumper does not affect the administrator password. If the administrator password is set, you must replace the I/O board. 7 J16 Flash page swap The default position is a jumper installed on pins 2 and 3. Changing the position of this jumper will change which of the two pages of flash ROM is used when the system is started. You can use this jumper to recover from a BIOS flash update problem. To do this: 1. Power-off the system. 2. Move jumper J16; then, power-on the system. 146 Netfinity Server HMM
