System Board Jumper Settings
The system board has one jumper block: clear password jumper block 7G4. Jumper block 7G4 is
on the SO-DIMM side of the system board (see "System Board Connectors, Sockets, and
Jumpers" in Section 4 for jumper location). The jumper block is briefly described in the
following paragraphs.
Jumper block 7G4 is a two-pin jumper block for clearing the system password if the password is
forgotten. The factory setting for 7G4 is pins 1 and 2 jumpered. To clear the password, the
system must be powered down, the jumper removed and reinstalled, and the system powered up.
Procedures for setting the jumper are included in Section 4. Specifications for the system board
are included in Section 9.
