Vodavi Starplus Digital 4896 has locked up twice in the last 2 weeks. When it happens, the phones go online then offline repeatedly, and the system is generally sluggish. In both cases this was corrected with a power-cycle. Input power tests ok, and the system is on a new UPS. When we replaced the UPS a couple months ago the power problem caused by the failed UPS ended up taking out an analog station card. I'm thinking it's a failing power supply or CPU, but wanted to get some more system-specific experienced answers. It could also be that more was damaged by the previous UPS than I realized. Thanks!

Check the 5 and 12 volt outputs. This actually sounds like more of an issue with the memory battery on the CPB failing. I'd get a backup of the database now while you still can.

Do the 5 or 12 volt outputs charge the memory battery? If the system is recovering after a power-cycle, how would the mem battery be affecting live operation?

It's old. I bet something is deterioating on just about every card. The power off discharges a bunch of caps and after the power is turned on and they warm up they start acting up again.

I've tried using the "it's old" argument. So far all it's gotten me is little sympathy.

If you don't have immediate backup parts, try disconnecting a card or two to lighten the load on the system. If that helps, it points to the power. but as Derrick said, other cards may be failing too. If the customer is determined to extend the life of this system, install a new memory battery and mark up any other parts to cover yourself for callbacks. The 4896 was discontinued 11 years ago and any part you find will be old.

I know that SIBs, serial interface modules, can casuse this kind of thing as well.

Is it normal to have to reset the clock following a power-cycle?

Your memory battery may be going bad if you have to reset the clock. It isn't totally discharged or you would lose everything.

Does anyone have a documented test procedure for verifying in-spec voltages from the power supplies? Based on the Installation manual, it looks like you're supposed to rely only on the LEDs, but I have a feeling the test point specs are documented somewhere. Also, if you have the test procedure, do you have the allowed voltage variance?
