Chapter 3 Installing the Cisco 7204
General Installation
•
There must be approximately 19 inches 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.
•
Provide an adequate chassis ground (earth) connection for your router chassis.
Note
We strongly recommend that you provide a chassis ground connection. Refer to the
following section “
Providing a Chassis Ground Connection for the Router Chassis ” for
instructions.
Following are the steps for installing the Cisco 7204 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.
Warning To prevent damage to the chassis or personal injury, never attempt to lift or tilt the Cisco 7204 using
the port adapter handles or the I/O controller handle; they are not designed to support the weight of
the router.
Always have someone help you when installing the Cisco 7204.
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 three inches 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 of clearance at the front and rear of the chassis.
This completes the general installation.
To install the cable-management brackets on the Cisco 7204, 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 3-9 .)
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.
This completes the steps for installing the cable-management brackets on the Cisco 7204.
