If you do have a board malfunction, turn the power back off

and re-seat the board; if you didn’t insert the mounting screws,

do so. Power the system back up and check the boards again. If

you still have a malfunction, try inserting a different CPU or

services board; if the other board works, you know there is a

problem with your original board. Should you experience any

of these malfunctions, contact your Comdial technical-services

representative for more troubleshooting tips and technical

support.

Always remember to turn the power off before you insert the

next board to prevent damaging the boards. Some of the

boards, the station and line boards specifically, have pre-power

jacks that allow you to work with the power on. Other boards,

like the AUX. board, require that you have the power off

before doing any work. It’s a good idea to turn the power off

just in case.
