Cisco Cisco Web Security Appliance S360 安装指南

This section provides information about preparing for installation, and it includes the following topics:

To prevent the system from overheating, do not operate it in an area that exceeds the maximum 
recommended ambient temperature of: 35° C (95° F). 
Statement 1047

The plug-socket combination must be accessible at all times, because it serves as the main 
disconnecting device.
Statement 1019

This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that 
the protective device is rated not greater than: 250 V, 15 A.
Statement 1005

Installation of the equipment must comply with local and national electrical codes.
Statement 1074

To ensure proper airflow it is necessary to rack Content Security Appliances using rail kits. Physically 
placing the units on top of one another or “stacking” without the use of the rail kits blocks the air vents 
on top of the appliances, which could result in overheating, higher fan speeds, and higher power 
consumption. We recommend that you mount your appliances on rail kits when you are installing them 
into the rack because these rails provide the minimal spacing required between the appliances. No 
additional spacing between the appliances is required when you mount the units using rail kits.

Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems 
such as the Cisco Content Security Appliances, which can have substantial current draw fluctuations 
from fluctuating data traffic patterns.
