Network symbol for a router, a circle or box with outward arrows, that connects separate IP networks.

## In plain English

### What does Network router mean?

Routers forward traffic between separate networks, such as a plant network and a remote access link. Drawings commonly use a circle with four outward arrows. Industrial routers may also include cellular modems and firewall functions.

### A simple example

On electrical drawings the router appears in communication cabinets with its supply, antenna connection for cellular types and its WAN and LAN ports. Remote access to protection or SCADA equipment often passes through it. The symbol does not show routing tables, VPN configuration or firewall rules.

### What the drawings help you do

Identify WAN and LAN sides. Check for cellular antennas. A switch forwards within one network; a router connects networks and often enforces security policy.

### This particular reference
