Installation Warnings and Guidelines
Warning
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
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
Warning
This unit is intended for installation in restricted access areas. A restricted access area can be accessed
only through the use of a special tool, lock, and key, or other means of security.
Statement 1017
Caution
To ensure proper airflow it is necessary to rack the servers 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 servers, which
could result in overheating, higher fan speeds, and higher power consumption. We recommend that you mount
your servers on rail kits when you are installing them into the rack because these rails provide the minimal
spacing required between the servers. No additional spacing between the servers is required when you mount
the units using rail kits.
Caution
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.
When you are installing a server, use the following guidelines:
• Plan your site configuration and prepare the site before installing the server. See the
Preparation Guide

for the recommended site planning tasks.
