Protective Vent

The protective vent on the router base (see
that can be caused by changing temperatures in the router installation environment. This prevents
pressure from building up and damaging enclosure seals, exposing sensitive components to water. The
vent also protects the router interior from dust, dirt, water, and other environmental elements.

AC Power Supply

The router has two power sources, the AC power supply and the battery backup units.
The AC power supply connector on the router base (see
