Return the J5 jumper to its normal position when the front panel signature analysis is complete.

Secondary SA

For secondary SA troubleshooting, connect the signature analyzer as shown in Table 3-3. Use a jumper wire and short U4 pin 21 to common (U4 pin 20). Check for the waveforms in Figure 3-4 and the signatures in Table 3-8 for the secondary SA. When the secondary signature analysis is complete, disconnect the jumper on U4 pin 21.

Jumpering pins 1 and 2 skips the internal selftest when the unit is turned on.

Jumpering pins 3 and 4 places U37 in SA mode. Jumpering pins 5 and 6 is the normal/operating position of the jumper.
