a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if

you are uncertain that suitable grounding is available. Statement 1024

Warning

Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages

and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other

equipment; and they direct theflow of cooling airthrough the chassis. Do not operate the system unless all cards,

faceplates, front covers, and rear covers are in place. Statement 1029

Warning

Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Statement 1030

Warning

To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the handles on

modules (such as power supplies, fans, or cards); these types of handles are not designed to support the weight

of the unit. Statement 1032

Warning

Ultimate disposal of this product should be handledaccording to all national laws and regulations. Statement 1040

Installing the Chassis

You can set the chassis on a desktop or install it in a rack. See the applicable instructions in the following sections:

• Rack-Mounting the Chassis, page 9

• Installing on a Desktop, page 11

Note Cisco 3725 routers are not designed for wall-mounting.

Caution Your chassis installation must allow unrestricted airflow for chassis cooling. For mounting in a 19-inch (48.26-cm)

rack, be sure to install the wide bracket (marked RIGHT) on the side where the cooling fans are located. For

installation on a desktop, keep at least 1 inch (2.54 cm) of clear space beside the cooling fans.

Caution To prevent damage to the chassis, never attempt to lift or tilt the chassis by the plastic panel on the front. Always

hold the chassis by the metal body.

Rack-Mounting the Chassis

You can install the Cisco 3725 router in a 19-inch (48.26-cm) rack with the following chassis orientations:

• Center mounting—Brackets attached in the center of the chassis with either the front panel or the rear panel facing forward

• Front mounting—Brackets attached at the front of the chassis with the front panel facing forward

• Rear mounting—Brackets attached at the rear of the chassis with the rear panel facing forward
