Rack Mounting Guidelines
Figure 1 Attaching an ESD-Preventive Strap
• Avoid contact between the component and clothing. The wrist strap protects the component only
from ESD voltages on the body; ESD voltages on clothing can still cause damage.
Rack Mounting Guidelines
Before installing the Cisco 10720 Internet Router in a 19-inch EIA, 23/24-inch EIA or ETSI equipment
rack, consider the following general rack-mounting guidelines:
• Ventilation Guidelines, page 5
• Rack Mounting Clearance Guidelines, page 7
• Multiple Routers in a Rack Maintenance Guidelines, page 7
Ventilation Guidelines
Caution The fan assembly is located in the back of the router chassis. Air flow in the front and back of the router
should not be blocked.
The following section provides information and guidelines to provide adequate ventilation for the
Cisco 10720 Internet Router:
• Install the chassis in an enclosed rack only if the rack has adequate ventilation or an exhaust fan; use
an open rack when possible.
• A ventilation system that is too powerful in an enclosed rack can also prevent cooling by creating
negative air pressure around the router and redirecting the air away from the air intake vent. If
necessary, operate the router with the rack door open or in an open rack.
• Make sure the air baffle located between the fan assembly and power supply is properly seated to
assist in cooling the router.
