Locations”).
4. Remove any subassemblies blocking access to the jumper (see Section 3, “Disassembly and
Reassembly,” for procedures).
5. Change the jumper setting by moving the jumper to or from the pins as indicated in the
jumper settings tables (see “System Board Jumper Settings” in Section 2).
For some functions, a jumper is moved or removed for only a few
seconds. The jumper change takes effect immediately, even if the jumper is moved back to its
original setting. Check the jumper settings tables carefully and be sure to move the correct
jumper so you don’t inadvertently change important settings.
6. Replace any removed disassemblies and the system cover (see Section 3).
