Do you mean that you think it is the switch? If so, you should be able to go down to radioshack and purchase a new one to replace it...

#1. You should call APC Technical Support. It's free, and they will help you. You should get voltage even without a load on the unit.

#2. There is a Tripple-Slot unit for this device. It's specific for the Silcon based units. Read the manual, and there is a PN that you need for it. If it doesn't say SILCON, then it won't work. (I tried).

I have had the problem of APC's PowerChute software forgetting my password. No joke. I write these things down when I set them.

Two options:
Call APC support. They are awesome. Smart, well spoken and free. You will need the model number and serial number from your UPS. (800) 555-2725
Remove and reinstall the APC software. During the reinstallation you should be prompted to set a new password.

Vote for this solution if it helps.
