Installing the Cisco 7204
This chapter explains the procedures for installing and starting the Cisco 7204. The chapter
contains the following sections:
•Rack-Mounting the Cisco 7204
•General Installation
•Connecting Port Adapter Cables
•Connecting I/O Controller Cables
•Connecting Power
•Starting the Cisco 7204
A rack-mounting kit is included in the shipping container for mounting the Cisco 7204 in
a standard 19-inch-wide equipment rack or in a 19-inch Telco-type rack. The kit is not
suitable for use with other racks, such as 23-inch Telco racks. If you are installing an
equipment shelf or using mounting hardware other than that supplied with the chassis,
review the guidelines in the section “Equipment Racks” in the chapter “Preparing for
Installation,” then proceed to the section “General Installation” in this chapter.
If you plan to install your Cisco 7204 in an equipment rack, proceed to the section “General
Installation” later in this chapter.

Rack-Mounting the Cisco 7204
The chassis mounts to two rack posts with brackets that attach to the sides of the chassis.
The inside width between the two posts or mounting strips (left and right) must be at least
17.00 inches (43.18 cm).
Some equipment racks provide a power strip along the length of one of the mounting strips.
Figure 3-1 shows a typical 19-inch equipment rack with a power strip along one of the back
posts. If your rack has this feature, consider the position of the strip when planning fastener
points and ensure that you will be able to pull port adapters and other FRUs straight out of
their respective slots.
The inlet and exhaust ports for cooling air are located on the right and left of the chassis,
respectively, so multiple routers can be stacked in a rack with little or no vertical clearance.

Installing the Brackets on the Chassis
Before you install the brackets, the chassis should be unpacked, and you should have
already verified the router hardware configuration.
Warning After attaching the brackets, and to avoid injury, we recommend that two people
install the chassis in the rack. (One person should support the chassis in the rack while the
second person installs the fasteners.) To see translated versions of this warning, refer to the
publication Regulatory Compliance and Safety Information for the Cisco 7200 Series
Routers (Document Number 78-3419-xx) that accompanied your Cisco 7204.
To install the brackets on the chassis, complete the following steps:
Step 1 Locate the threaded holes in the chassis sides (at the port adapter end of the
chassis). (Refer to Figure 3-2.)
Step 2 Align the first bracket to the right side of the chassis. (The brackets are identical
and can be mounted on either side of the chassis.) Hold the bracket in the
orientation shown in the Figure 3-2.

Warning To prevent injury, review the safety precautions in the chapter “Preparing for
Installation,” before installing the router in a rack. To see translated versions of this
warning, refer to the publication Regulatory Compliance and Safety Information for the
Cisco 7200 Series Routers (Document Number 78-3419-xx) that accompanied your
Cisco 7204.
Installing the Chassis in the Rack
After installing the brackets on the chassis, mount the router by securing the brackets to two
posts or mounting strips in the rack using the eight slotted screws provided. Because the
brackets support the weight of the entire chassis, be sure to use all eight slotted screws to
fasten the two chassis brackets to the rack posts. Figure 3-3 shows a typical installation in
a standard, 19-inch equipment rack with four mounting posts. Figure 3-4 shows a typical
installation in a Telco-type rack, which usually has two center posts and is bolted to the
floor. If you are mounting the router in a rack with four posts, use all eight slotted screws
to mount the chassis on the front posts.

Step 2 Make sure that your path to the rack is unobstructed. If the rack is on wheels,
ensure that the brakes are engaged or that the rack is otherwise stabilized.
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
designedtosupporttheweightoftherouter.Alwayshavesomeonehelpyouwheninstalling
the Cisco 7204. To see translated versions of this warning, refer to the publication
Regulatory Compliance and Safety Information for the Cisco 7200 Series Routers
(Document Number 78-3419-xx) that accompanied your Cisco 7204.
Note Two people should perform Step 3 through Step 6.
Step 3 Position the chassis so that the end with the brackets attached is closest to you;
then lift the chassis and move it to the rack. To prevent injury, avoid sudden
twists or moves.
Step 4 Slide the chassis into the rack, pushing it back until the brackets meet the front
mounting strips or posts on both sides of the equipment rack.
Step 5 While keeping the brackets flush against the posts or mounting strips, position
the router so the holes in the brackets are aligned with those in the mounting
strips.
Step 6 From the front of the rack, insert all eight 10-32 x 3/8 slotted screws (four on
each side) through the brackets and into the mounting strip (use the top and
bottom bracket holes, as shown in Figure 3-4). Using a 1/4-inch, flat-blade
screwdriver, tighten all the screws.
This completes the rack installation. Proceed to “Connecting Port Adapter Cables” in this
chapter to continue the installation.

General Installation
General Installation
The router should already be in the area where you will install it, and your installation
location should already be determined. If not, refer to the section “Site Requirements” in
the chapter “Preparing for Installation.”
When installing the Cisco 7204 on a workbench or tabletop, ensure that the surface is clean
and in a safe location and that you have considered the following:
•The router requires at least three inches of clearance at the inlet and exhaust vents (the
right and left sides of the router).
•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 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).
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
designedto support the weight of the router.Always havesomeone help you wheninstalling
the Cisco 7204. To see translated versions of this warning, refer to the publication
Regulatory Compliance and Safety Information for the Cisco 7200 Series Routers
(Document Number 78-3419-xx) that accompanied your Cisco 7204.

Connecting Port Adapter Cables
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. Proceed to the following section, “Connecting Port
Adapter Cables,” to continue the installation.
Connecting Port Adapter Cables
The instructions for connecting the cables for each port adapter installed in the Cisco 7204
are contained in the respective configuration note for each port adapter. For example, if you
are connecting the cables for a Token Ring port adapter, refer the configuration note PA-4R
Token Ring Port Adapter Installation and Configuration (Document Number 78-2661-xx).
This configuration note accompanies every Token Ring port adapter that is shipped from
the factory as an installed item in a Cisco 7204 or as a FRU. The document is also available
on the Cisco Connection Documentation, Enterprise Series CD, and on Cisco Connection
Online (CCO).
Connecting I/O Controller Cables
The console and auxiliary ports for the Cisco 7204 are located on the I/O controller. The
I/O controller also has an optional Fast Ethernet port (refer to Figure 3-5). This section
contains connection equipment and pinout information for the console, auxiliary, and Fast
Ethernet ports on the I/O controller.
