Replaced INNPM12 with INNPM01
We have a setup of Bailey infi90 system in which we used IMMFP02, INNPM01, INNIS01 and NICL01. Now i want to replaced INNPM01 with INNPM12. simply plug out the previous one INNPM01 and match the dip switch settings and then plug in INNPM12 But INNIS01 and INNPM01 both on fault. Please told me the procedure for this replacement.
I would strongly recommend you to consult the user manuals first, then post on the forum if that does not help you.
Based on your photo I find the following errors in the user manual;
NIS01 error code: Loopback test failure
NPM12 error code: NIS handshake failure
From this it is my understanding is that the NPM12 cant communicate with the NIS01, this due to the NIS01 has failed since it cannot connect to the coax loop;
Check check the module power at the MMU backplane and check the I/O power on the termination unit/module. Replace the cable to the LIS/NIS/ICLor the termination device itself. If the problem still exists replace the LIS/NIS/ICL
Could it be that you have swapped the NIS/NPM rack positions during the upgrade or not inserted the NIS01 module properly?
