NEC NEAX IPS2000 Troubleshooting

[herestone]

Hi All,

Can someone help me with my concerns on NEC NEAX IPS2000?

Actually, our client has 3 PIMs Named PIM 0 PIM 1, and PIM 2 . They have a problem with the PIM 2 (all Analog Local) Status of the LED cards are all blinking-PIM 0 and PIM 2 are working fine. I checked the programming and thought that the local assignment disappear but all local programming all are set. Please help me what are the possible cause that the PIM 1 is down all no dial tone. Is it possible that the power supply is defective or any suggestion what would i Checked to Isolate the problem?

Thank you ..

Check the PSU voltages. Push the + meter probe into the back of the power supply plug at the back left of the PIM, and the - probe to ground. You should get -5 vdc and -27 vdc.

Its the PSU. I have had that happen many a time. Replace it
