Overview
Warnings, cautions, and guidelines to follow when physically installing an appliance.
These guidelines apply when installing an appliance:
-
Plan your site configuration and prepare your site before installing the appliance. For information about recommended site planning and preparation tasks, see the Cisco UCS Site Preparation Guide.
-
Ensure that there is adequate space around the appliance for servicing and airflow. Air enters through the front of the appliance and exits through the back.
-
Ensure that the site's air conditioning meets the thermal requirements listed in Environmental specifications.
-
Ensure that the cabinet or rack meets the requirements in Review the rack requirements.
-
Ensure that the site's power meets the requirements in Power supply specifications. If available, use a UPS to protect against power failures.
-
Carefully review the cautions and warnings.
To ensure proper airflow, rack the appliances using rail kits. Stacking units without rail kits blocks the air vents on top of the appliances. This results in overheating, increased fan speeds, and greater power consumption. Mount your appliances on rail kits during installation to ensure the required minimum spacing between units. No additional spacing is required when units are mounted using rail kits.
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.
