Chapter 2 Router Hardware Description
Hardware Features Detailed Description
100BASE-T Fast Ethernet Connector
The router feature an external Fast Ethernet (FE) connector (see Figure 2-7) that enables you to connect
the router to an Ethernet hub or switch without opening the chassis. The connector is connected to one
of the four
Fast Ethernet Ports inside the router chassis.
Specifications
Protective Vent
The protective vent on the router base (see Figure 2-7) 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, the AC power supply and the battery backup units.
The AC power supply connector on the router base (see Figure 2-7) is the connection from the to AC
power. If AC power is longer being supplied to the router, the battery backup units will continue to
supply power to the router until power is restored. For details about how the battery backup units
operate, see the chapter
Installing Battery Backup Units.
