Warnings, cautions and guidelines to follow when physically installing an appliance.
When you install an appliance, follow these guidelines:
-
Plan your site configuration and prepare the site before installing the appliance. See the Cisco UCS Site Preparation Guide for help with the recommended site planning and preparation tasks.
-
Ensure that there is adequate space around the appliance to enable servicing, and for adequate airflow. The airflow in this appliance is from front to 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 listed in Review the rack requirements.
-
Ensure that the site's power meets the requirements listed in Power specifications. If available, use a UPS to protect against power failures.
-
Before you install, operate, or service a server, review the Regulatory Compliance and Safety Information for Cisco UCS C-Series Servers for important safety information.
-
Review the following cautions and warnings. Note that Statements 1024 and 1099 are specific to the 112-core Catalyst Center appliance.
To ensure proper airflow, it is necessary to rack the appliances using rail kits. Physically placing the units on top of one another or stacking without the rail kits blocks the air vents on top of the appliances, which could result in overheating, higher fan speeds, and higher power consumption. We recommend that you mount your appliances on rail kits when you are installing them into the rack because these rails provide the minimal spacing required between the appliances. No additional spacing between the appliances is required when you mount the units using rail kits.
Avoid UPS models that use ferroresonant technology. These UPS models can become unstable with systems such as the Cisco UCS, which can have substantial current-draw fluctuations because of fluctuating data traffic patterns.
