FP2000 series backup battery life?

[pauldw]

It says in the user manual for the fp2000 series network controllers that they have an internal battery-backed clock. Could anyone tell me roughly how long it would last for in the event of a main power failure to the unit??

The battery back-up should last approximately 190,000 hours.

How to replace it?
Because my FP-2000 will lost the time after power failure.

If your concern is that the battery has died on the FieldPoint, it is advised to call in to National Instruments and have it repaired.  How old is your FP-2000?
