Statement 1074
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.
•
Ensure that the air-conditioning meets the thermal requirements listed in the
Server Specifications
.
•
Ensure that the cabinet or rack meets the requirements listed in the
“Rack Requirements” section on
page 2-4
.
•
Ensure that the site power meets the power requirements listed in the
Server Specifications
. If
available, you can use an uninterruptible power supply (UPS) to protect against power failures.
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.
