Chapter 2 Installing the Cisco ISA 3000 Industrial Security Appliance
Installing the Cisco ISA 3000
Caution
Airflow around the device must be unrestricted. To prevent the device from overheating, ensure these
minimum clearances:
– Top and bottom: 1.0 inches (25 mm)
– Exposed side (not connected to the module): 1.0 inches (25 mm)
– Front: 1.0 inches (25 mm)
When installing the device, ensure you are following these guidelines:
•
Temperature surrounding the unit does not exceed 140°F (60°C).
Note
When the device is installed in an industrial enclosure, the temperature within the enclosure
is greater than normal room temperature outside the enclosure.
The temperature inside the enclosure cannot exceed 140°F (60°C), which is the maximum
ambient enclosure temperature of the device.
•
Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent
lighting fixtures.
•
Connect the unit only to a Class 2 DC power source.
•
Contact your Cisco TAC if tighter spacings are required.

Installing a DIN Rail
You can use either the 7.5-mm or the 15-mm thick DIN rail for the Cisco ISA 3000. Secure the DIN rail
to the mounting surface approximately every 7.8 inches (200 mm) and use end-anchors appropriately.
The device ships with a spring-loaded latch on the rear panel for a mounting on a DIN rail. See
Figure 2-1
.
Caution
Do not stack any equipment on the device.
