Cisco Systems 2130 Manual De Usuario

c shows a 2-post (telco-type) rack. This rack is an open frame consisting of two posts tied 

together by a crossbar at the top and a floor stand at the bottom.

This type of rack is usually secured to the floor and sometimes to an overhead structure or wall for 
additional stability. The Cisco ADE 2130 or 2140 Series appliance can be installed in this rack either in 
a front-mounted position or a mid-mounted position.

In the front-mounted position, you secure the appliance rack-mounting brackets directly to the rack 
posts.

In the mid-mounted position, you secure a set of optional mid-mount brackets to the rack posts. The 
appliance rack-mounting flanges are then secured to the mid-mount brackets. The mid-mounted 
position moves the center of gravity closer to the appliance and closer to the vertical axis of the rack 
posts, which adds to the stability of the rack installation.

Before installing your Cisco ADE 2130 and 2140 Series appliance in a rack, review the following 
guidelines:

Two or more people are required to install the appliance in a rack.

Ensure that the room air temperature is below 95°F (35°C).

Do not block any air vents; usually 6 inches (15 cm) of space provides proper airflow.

Plan the appliance installation starting from the bottom of the rack.

Do not extend more than one appliance out of the rack at the same time.

Connect the appliance to a properly grounded outlet.

Do not overload the power outlet when installing multiple devices in the rack.

Do not place any object weighing more than 110 lb (50 kg) on top of rack-mounted devices. 

The location of your appliance and the layout of your equipment rack or wiring room are important 
considerations for proper operation. Equipment placed too close together, inadequate ventilation, and 
inaccessible panels can cause malfunctions and shutdowns, and can make maintenance difficult. Plan for 
access to front and rear panels of the appliance.

The following precautions will help you plan an acceptable operating environment for your appliance 
and will help you avoid environmentally caused equipment failures:

Ensure that the room where your appliance operates has adequate circulation. Electrical equipment 
generates heat. Without adequate circulation, ambient air temperature may not cool equipment to 
acceptable operating temperatures (see the 

). 

Ensure the site of the rack includes provisions for source AC power, grounding, and network cables.

Allow sufficient space to work around the rack during the installation. You need:

At least 3 feet (9.14 m) adjacent to the rack to move, align, and insert the appliance.

At least 24 inches (61 cm) of clearance in front of and behind the appliance for maintenance 
after installation.

To mount the appliance between two posts or rails, the usable aperture (the width between the inner 
edges of the two mounting flanges) must be at least 17.7 inches (45.0 cm).

If you use a 2-post (telco-type) rack, the weight of several appliances is cantilevered off of the two 
rack posts. Make sure that:
