Avoid uninterruptible power supply (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.
Caution
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 accessing 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 Environmental Specifications,
on page 64.
• Ensure that the site power meets the power requirements listed in the Power Specifications, on page 63.
If available, you can use an uninterruptible power supply (UPS) to protect against power failures.
• Before attempting rack installation of the server, you will find it helpful to note important information,
such as the server's MAC address and serial number, off of the label at the top right corner of the server.
