Chapter 3 Router Hardware Description
Hardware Features Detailed Description
Protective Vent
The protective vent on the router base (see
Figure 3-7
) relieves pressure buildup inside the router chassis
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: an AC power supply and the battery backup units.
The AC power supply connector on the router base (see
Figure 3-7
) is the connection to AC power. If
AC power is no longer being supplied to the router, the battery backup units will continue to supply
power to the router until AC power is restored. For details about how the battery backup units operate,
see the
“Installing Battery Backup Units”
chapter.
