3745 FRU Exchange Procedure
Installation Procedure
1. Install the new SMUX cassette.
2. Fasten the thumb screw holding the SMUX
cassette to the board. Finger strength is
enough. Do not use tools.
3. Replace the SMUX cables.
4. Set the XMIT level according to the table
below. Refer to Figure 4-53 on page 4-42 for
the sliding switches.
5. Re-install the SMUX cover with the 2 screws.
Refer to Figure 4-51 on page 4-41.
6. Close the rear door.
7. Referring to Chapter 3, “How to Run 3745
Diagnostics” on page 3-1, run the same diag-
nostic you ran before you exchanged the
FRU, then go to “Action to Take After a Diag-
nostic Run or an FRU Exchange” on
page 4-99.

Note
If exchanging the SMUX does not solve the problem, you should test the voltage levels at the SMUX
test points. If the voltage levels are not correct, suspect the Power Supply 1.
For test point pin location, see page YZ739.
For voltage tolerances, see
IBM 3745 Hardware Maintenance Reference, SY33-2066.
