It may be the battery on the I/O module. Some are a soldered-in coin battery and others are built in to a Dallas/Mostek/Maxim chip that is also used for the clock/calendar. If soldered in, you can replace the battery if handy with a soldering iron. If the Dallas chip, get a DS1248Y-70 from Mouser and replace it, then re-initialize. Repeat in about six to ten years, less if you leave the box unplugged for a very long time. -- Jay Hennigan - CCIE #7880 - Network Engineering - j...@impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV _______________________________________________ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
