Troubleshooting

Service

Checking for Heat Damage

Inspect the assembly for signs of abnormal internally generated heat such as 
discolored printed circuit boards or components, damaged insulation, or 
evidence of arcing.

Checking Switches/Jumpers

Verify that the interrupt priority jumpers are set correctly (factory set at level 1). 
Verify that the logical address switch is set correctly (factory set at 144). Verify 
that the pull-up enable switches are set correctly (factory set to disable). Verify 
that the port/flag combine switches are set correctly (factory set to Disable on all 
ports). Refer to the Keysight E1458A User’s Manual for procedures to set or 
check these switches/jumpers.

Checking the Keysight E1458A PCA

Check the following:

–

Verify that fuse F101 is good (see the replacement procedure).

–

Check connectors P1, P2, J4A, J4B, J5A, J5B for damage.

–

Perform Test 2-1 in Chapter 2. Replace the module if the test fails.

Self-test Error Codes

Table 4-3 shows the self-test error codes for the module. The meaning of each 
code is given in the right-hand column. If a self-test failure occurs, cycle power 
and repeat the test. If the problem reoccurs, the device may need repair.
