Chapter 3 Installing the Cisco 7206
General Tabletop or Workbench Installation
• The router should be installed off the floor. (Dust that accumulates on the floor is drawn into the
interior of the router by the cooling fans. Excessive dust inside the router can cause overtemperature
conditions and component failures.)
• There must be approximately 19 inches (48.3 cm) of clearance at the front and rear of the router for
installing and replacing router FRUs, or accessing network cables or equipment.
• Port adapter and power supply filler panels are installed.
• The router will receive adequate ventilation (it is not being installed in an enclosed cabinet where
ventilation is inadequate).
• If you plan to install the cable-management brackets on the front of the chassis, you have unpacked
and set aside the two cable-management brackets and four M4 x 8-mm Phillips flathead screws.
• An adequate chassis ground (earth) connection for your router chassis.
Note We strongly recommend that you provide a chassis ground connection. Refer to the
“Providing a Chassis Ground Connection for the Router Chassis” section on page 3-12 for
instructions.
Following are the steps for installing the Cisco 7206 on a workbench or tabletop:
Step 1 Remove any debris and dust from the tabletop or workbench, as well as the surrounding area. Also make
sure your path between the router and its new location is unobstructed.
Step 2 On the chassis, ensure that all captive screws on the network processing engine, the I/O controller, and
each power supply are tightened and the port adapter levers are in the locked position.
Step 3 Lift the chassis by placing your hands around the chassis sides and lifting the chassis from underneath.
To prevent injury, avoid sudden twists or moves.
Step 4 Place the router on the tabletop or workbench.
Step 5 Ensure that there is at least 3 inches (7.62 cm) of clearance at the inlet and exhaust vents of the router
and no exhaust air from other equipment will be drawn into the chassis. Also, ensure that there is
approximately 19 inches (48.3 cm) of clearance at the front and rear of the chassis.
This completes the general installation.
Installing the Cable-Management Brackets
To install the cable-management brackets on the Cisco 7206, complete the following steps:
Step 1 Locate the threaded holes in the front sides of the chassis.
Step 2 Align the first cable-management bracket to the threaded holes in the right side of the chassis. (Refer to
Figure 3-5.)
Step 3 Thread two M4 x 8-mm Phillips flathead screws through the bracket and into the chassis. Use a number
2 Phillips screwdriver to tighten the screws.
Step 4 Repeat Step 1 through Step 3 for the other cable-management bracket.
