- Not to long ago, I had a capacitor die in our DN 10000. Since then, the silly
- machine was up and down like a yo-yo. It would stay "on-line" no longer than
- two hours before the "5V undervoltage" light would come on, and the DN10000
- would go off.
-
- As a bold measure, I dipped a little of the compound shown below on each pin
- of each "power brick" and fired the DN10000 up. It has been one week since
- then (not one hour). I even used the computer to backup our network today! It
- hasn't been long enough to say how well this idea will work, but this could be
- something to try for the needy sys-admins (without maint. support) out there.
