Chapter 2 Preparing to Install the Cisco ADE 2130 and 2140 Series Appliance
Preparing Your Site for Installation
–
The weight of several appliances does not make the frame unstable.
–
The frame is bolted to the floor and is secured to the building structure using either wall brackets
or overhead brackets.
• Use appropriate strain-relief methods to protect cables and equipment connections.
• To avoid noise interference in network interface cables, do not route them directly across or along
power cables.
• Always follow ESD-prevention procedures as described in the “Preventing Electrostatic Discharge
Damage” section on page 2-5 to avoid damage to equipment. Damage from static discharge can
cause immediate or intermittent equipment failure.
Airflow Guidelines
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 the flow of cooling air through the chassis.
Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.
Statement 1029
To ensure adequate airflow through the equipment rack, it is recommended that you maintain a clearance
of at least 6 inches (15.24 cm) at the front and the rear of the rack.
If airflow through the equipment rack and the appliances that occupy it is blocked or restricted, or if the
ambient air being drawn into the rack is too warm, an overtemperature condition within the rack and the
appliances that occupy it can occur.
The site should also be as dust-free as possible. Dust tends to clog the appliance fans, reducing the flow
of cooling air through the equipment rack and the appliances that occupy it. This reduction increases the
risk of an overtemperature condition.
Additionally, the following guidelines will help you plan your equipment rack configuration:
• Besides airflow, you must allow clearance around the rack for maintenance.
• When mounting an appliance in an open rack, ensure that the rack frame does not block the front
intakes or the rear exhausts.
Temperature and Humidity Guidelines
Table 2-1 on page 2-10 lists the operating and nonoperating environmental site requirements for the
Cisco ADE 2130 and 2140 Series appliance. The appliance normally operates within the ranges listed;
however, if a temperature measurement approaching a minimum or maximum parameter indicates a
potential problem. Maintain normal operation by anticipating and correcting environmental anomalies
before they approach critical values by properly planning and preparing your site before you install the
appliance.
Warning
To prevent the system from overheating, do not operate it in an area that exceeds the maximum
recommended ambient temperature of:
95
°F (35°C). Statement 1047
