# 2.3 Indicators

There are eight indicators on the EZR34T router.

The SIM card indicators are in the top left corner of each SIM card slot. They will turn on when a related SIM slot is activated.

On the bottom side of the motherboard are Wi-Fi, System, Mobile, Power, WAN, and LAN indicators, as the image below shows.
