Icon Library for network diagrams

mMontana

Sometimes it's asked to me to realize network diagrams and documentation for my installations, so i must use network diagram software or simply vector design (LibreOffice Draw) for explain network structure and devices involved.

I'd like to use vector-based icons for Zyxel appliances and network products, but i was not able to find them.

Is there any place where i can find them?
