Configuration Jumpers Intel® Server Board SE7505VB2 9. Configuration Jumpers This section describes configuration jumper options on the Intel Server Board SE7505VB2. 9.1 System Recovery and Update Jumpers A 10-pin block (J4J1), located just below the DIMM connectors, provides a total of four 2-pin jumper blocks that are used to configure several system recovery and update options.

This section describes configuration jumper options on the Intel Server Board SE7505VB2.
9.1
System Recovery and Update Jumpers
A 10-pin block (J4J1), located just below the DIMM connectors, provides a total of four 2-pin
jumper blocks that are used to configure several system recovery and update options. The
figure below shows the jumper pins and their functions. The factory defaults are set to a
protected mode for each function.
Two jumpers are stored on four pins during normal operation. The BIOS bootblock write protect
jumper on pins 7-8 should be left on these pins at all times except when instructed by the BIOS
release notes to remove it. The jumper stored on pins 9-10 is used to perform different functions
depending on the pins it is placed. For normal operation, this jumper should be on the storage
pins.
