11.30 QSMU Installation Procedure
11.31
Install the QSMU in accordance with the
following steps (See Figure 4-7):
1) Remove the PCB from its protective packag-
ing.
2) Ensure the QSMU has been configured forthe
appropriate program options (refer to Para-
graphs

3) Slide the QSMU under the “System Frame
Ground Bar”, align and insert QSMU connec-
tor J2 into motherboard connector 520, en-
suring the side of the QSMU with the modular
connector goes on the right side. (The QSMU
is not silkscreened “+
RIGHT”.)
Apply firm,
even pressure to ensure proper mating of
connectors. Make sure the edge of the QSMU
opposite connector J2 snaps firmly into the
standoffs on the KSU motherboard.
4) Remove the “knock-out” from the KSU cover
SMDFUlTY
