When configuring TPS protection, SSN2PQ1 boards are not available (none of them appear in the "available working board" selection).
Warning messageNone
ProcessingIf N2PQ1 and N1PQ1 are mixed to configure TPS protection, the protection board must be N2PQ1. In this case, simply swap the N1PQ1 in slot #1 with the N2PQ1 veneer boards in any of the four slots #2, #3, #4, and #5 to configure the TPS protection group.
Root CauseIn TPS protection, N2PQ1 can protect N1PQ1; however, N1PQ1 cannot protect N2PQ1; because N2PQ1 has the E13 function (converting between E1E3) in addition to supporting the function of N1PQ1; therefore, you cannot use N1PQ1 to protect N2PQ1.
