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.

3-2 Cisco 7204 Installation and Configuration Guide

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.

Rack-Mounting the Cisco 7204

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.

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.

We recommend that you allow at least one or two inches of vertical clearance between the

router and any equipment directly above and below it.

Warning To maintain a low center of gravity, ensure that heavier equipment is installed

near the bottom of the rack. To see translated versions of this warning, refer to the

publication Regulatory Compliance and Safety Information for the Cisco 7200 Series

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

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.
