ERROR FIXED | There are two versions of the 940-0020 cable B and C. See http://lists.alioth.debian.org/pipermail/nut-upsuser/2005-August/000118.html for the B version. Im unsure of the C version, however the following is from the APC FAQ: Power fails while the system is in standby and the Back-UPS switches to battery power. The 20C is designed to mimic a mouse movement when it received an on battery signal from the Back-UPS. Therefore the computer will wake up and shutdown properly. The 20B cable does not have this functionality. | YES |
