Chapter 3 Installing the Router Setting Up the Chassis
Note Use 19-inch brackets (shown in Figure 3-4) to wall-mount the chassis. The small brackets provide
the most stable installation for the chassis.
To wall-mount the chassis:
Step 1 Attach the brackets as shown in Figure 3-17.
Figure 3-17 Attaching the Wall-Mount Brackets
Step 2 Attach the chassis assembly to the wall as shown in Figure 3-18, using screws and anchors that you
provide. We recommend the following:
•For the best support of the chassis and cables, attach the brackets so that the screws align with a
vertical wall stud. (See Figure 3-18.) This position will prevent the chassis from pulling away from
the wall when cables are attached.
•For the best ventilation of the chassis, mount the chassis with the power supply and fan at the top.
Make sure there is clearance between the router and the wall.

Identifying a Rollover Cable
Use a rollover cable to connect to the asynchronous serial console and auxiliary ports. You can identify
a rollover cable by comparing the two modular ends of the cable. Holding the cables side-by-side, with
the tab at the back, the wire connected to the pin on the outside of the left plug should be the same color
as the wire connected to the pin on the outside of the right plug. (See Figure 3-26.)
