Installation Guidelines
Warning
To prevent the system from overheating, do not operate it in an area that exceeds the maximum
recommended ambient temperature of: 40° C (104° F).
Statement 1047
Warning
The plug-socket combination must be accessible at all times, because it serves as the main
disconnecting device.
Statement 1019
Warning
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
Warning
Installation of the equipment must comply with local and national electrical codes.
Statement 1074
Caution Do not block the air vents on the top of the server’s cover. Do not stack another server directly on top of
the C220 server. Doing so blocks the proper airflow, which could result in overheating, higher fan
speeds, and higher power consumption.
Caution Avoid UPS types that use ferroresonant technology. These UPS types can become unstable with systems
such as the Cisco UCS, which can have substantial current draw fluctuations from fluctuating data traffic
patterns.
When you are installing a server, use the following guidelines:
• Plan your site configuration and prepare the site before installing the server. See the Cisco UCS Site
Preparation Guide for the recommended site planning tasks.
• Ensure that there is adequate space around the server to allow for servicing the server and for
adequate airflow. The airflow in this server is from front to back.
