Chapter 3 Installing the Cisco ADE 2130 and 2140 Series Appliance

Mounting the Cisco ADE 2130 and 2140 Series Appliance in a 2-Post Rack

Caution Some equipment racks are also secured to ceiling brackets, if necessary, due to the weight of the equipment in the rack. Make sure that the rack you are using to install the appliances is secured to the building structure.

•As mentioned in the “Airflow Guidelines” section on page 2-9, maintain a 6-inch (15.2-cm) clearance at the front and rear of the appliance to ensure adequate air intake and exhaust.

•Avoid installing the appliances in an overly congested rack. Air flowing to or from other appliances in the rack might interfere with the normal flow of cooling air through the appliances, increasing the potential for overtemperature conditions within the appliances. (See the “Overtemperature Protection (OTP)” section on page 1-16for more information about overtemperature conditions.)

•Allow at least 24 inches (61 cm) of clearance at the front and rear of the rack for appliance maintenance.

Caution To prevent appliance overheating, never install the appliance in an enclosed rack or room that is not properly ventilated or air conditioned.

•Follow your local practices for cable management. Ensure that cables to and from the appliances do not impede access to perform equipment maintenance or upgrades.

Mounting the Cisco ADE 2130 and 2140 Series Appliance in a 2-Post Rack

Typically, the Cisco ADE 2130 and 2140 Series appliance mounts to a 19-inch (48.3-cm) 2-post equipment rack with rack-mounting brackets that attach to the front sides of the appliance. The inside width between the two posts or mounting strips (left and right) must be at least 17.5 inches (44.45 cm). See the “Preparing Your Site for Installation” section on page 2-6for information about the types of equipment racks.

Even though the intake and exhaust for cooling air are located on the front and on the rear of the appliance, respectively, it is recommended that multiple appliances be stacked in a rack with at least a 1.5-inch (3.81-cm) vertical clearance.

Caution To prevent damage to the appliance, only use Cisco provided hardware and screws when installing the appliance.

To secure the appliance to the equipment rack, you must use the two 10-32 x 1/2-inch rack screws (see Figure 3-1 on page 3-4and Table 3-1 on page 3-4) for each side or follow your local practices for installing the appliance into your equipment rack. Ensure that the rack-mount brackets have been securely fastened. See the “Attaching the L Brackets to the Appliance” section on page 3-5for more information.

The following procedure provides a general outline for mounting the appliance into the equipment rack.
