Netvanta 7100 Locks up every night

[jjsweb]

I have a 7100 that locks up every night around 9:00 pm.  Links lights are still blinking but the phones are non responsive.  Shared lines have x's on them. I have to power-cycle the unit to bring it backup. I have updated the firmware to the latest version which worked for 3 days. Any suggestions?

Can you log in to the 7100 to check the logs or run debugging commands?

I would suspect some kind of power issue causing a glitch.  Light timer kicks on at night and causes a brownout, wedging the device.  Is it on a UPS?

The device was plugged into a UPS via a surge protector.  Why I'm not sure, but I plugged it into the UPS directly and have had no more issues.  Thanks for your help.
