Processor Baseboard Jumpers
The jumper blocks on the Processor Baseboard allow you to route Joint Test
Action Group (JTAG) Test Data In (TDI) and Test Data Out (TDO) signals
through different components on the Processor Baseboard. Additionally, jumper
blocks allow you to configure the host bus frequency, set the processor frequency,
and set other miscellaneous functions. To access these jumper blocks, expose the
top half of the Processor Baseboard by following the procedure in Chapter 6
“Installing an Additional Processor”. Figure A-9 shows where the jumper blocks
reside on the top half of the Processor Baseboard.
