Card* IRepair Action
Replace D/R card No. 28, check internal cable A 1 Zl or
A 1 Z3, and use device maintenance manual.
Use Personal Computer maintenance procedures.
• The diskette microcode level may be incorrect. Verify
feature/load diskette compatibility.
• Use the 3290 maintenance procedures.
Use the 3290 maintenance procedures.
Programming error. Check with program system
representative (PSR).
Replace card Nos. 24, 25, 26, 27.
Replace D/R card No. 30, check internal cable A1 Z2, and
use device maintenance manual.
• Run /3 test, and check for x in line 2. See page 2-9,
Example C.
• Disconnect unwanted device or recustomize responses
112 or 116, 117.
Replace card No. 12.
Replace card No. 13.
Replace card No. 14.
Verify I/O cable to LSC; replace LSC.
Replace card No. 11.
• Run the IML tests (Step 4).
• Replace diskette. Replace A 1 K2, drive unit, and its card.
Replace card Nos. 7,8,9,3,2, 1,4,5,6.
See code 0111, Figure 2-11.
See Chapter 6, Paragraph 6.1.3.
Request PSR assistance if problem persists.
Request PSR assistance if problem persists.
Check external communication cables, w/o 1M feature,
and perform A L T 2 (par. 5.3.1.2).
Replace card Nos. 13, 14, 18,20 with 1M feature.
Set the Local/Communicate switch to Communicate.
Run AL T 2 Test (Wrap); see paragraph 5.3.
Replace card Nos. 13, 14, 20.
Verify correct TP operation; contact host system operator.
Verify correct TP operation; contact host system operator.
Verify correct TP operation; replace card Nos. 13, 14.
Verify correct TP operation; replace card Nos. 13, 14.
If more than one device is failing, go to Step 5.
If a single 3290 is failing:
• Check for disconnected device cable.
• Isolate by swapping driver/receiver cards; see Figure 2-4.
• Use the 3290 maintenance procedures.
Use 3290 device maintenance procedures.
Use 3290 device maintenance procedures.
**If DDS Adapter, Integrated Modems, or Loop, Data Set Ready is generated within the 3274.
