Instructions for Models 270 and 820
See Locations and addresses for the model you are working on.
1. Is the SRC 1xxx 2600 or 2601?
v Yes: Continue with the next step.
v No: Go to step 3 (See page 408).
2. Perform the following:
a. Power off the frame.
b. Check that the tower card is connected and seated properly. See symbolic FRU “TWRCARD” on
page 470.
c. Check that the power supplies are connected and seated properly.
d. Power on the frame.
Is there an SRC 1xxx 2600 or 2601?
v No: Continue with the next step.
v Yes: Exchange the following FRUs one at a time. See Locations and addresses for location
information.
a. Memory cards if installed.
b. Processor cards if installed.
This
ends the procedure.
3. Is the SRC 1xxx 2602?
v No: Continue with the next step.
v Yes: Go to step 10 (See page 410).
4. Is the SRC 1xxx 2603?
v No: Continue with the next step.
v Yes: If you are working on a Model 270 with a FC 7104 system expansion unit, ensure that the FC
7014 ac power cable is plugged into both the system and the wall. Try to IPL the system, if you
cannot and the SRC persists, then the configuration ID may not be accurate. When you set the
system or frame ID, you must power down the system or frame with ac power applied. Verify that
both the system and the FC 7104 power cords are still plugged in.
Check the frame configuration ID:
a. Select function 07 on the system control panel. Press Enter (07** will be displayed).
b. Use the arrow keys to increment/decrement to subfunction A8. 07A8 will be displayed. Press
Enter (07A8 00 will be displayed).
c. Use the arrow keys to increment/decrement to the frame address of the box that you want to
check (07nn will be displayed, where nn is the frame address, usually 01 for system units).
Press Enter (07nn 00 will be displayed).
Note: The display on the addressed non-system unit should be blinking on and off. For a
system unit, press an arrow key (increment or decrement) twice to display the ID (first 07** will
be displayed then 07nn will be displayed, where nn is the Configuration ID).
d. The correct configuration ID is:
– 91 for a Model 270 without FC 7104 system expansion unit, without a removable
processor.
– 92 for a Model 270 without FC 7104 system expansion unit, with a removable processor.
– 95 for a Model 270 with FC 7104 system expansion unit, without a removable processor.
