Moving Server Chassis
A fully configured chassis is very heavy! Be aware of its weight, and follow these guidelines:
Caution
Do not try to lift the chassis without mechanical assistance! The chassis weighs 400 lbs (163.29 kg) fully
configured and 92 lbs (41.73 kg) empty. If available, use a scissor jack or other lifting device designed for
installing heavy equipment into data center racks.
• Disconnect all power and external cables before lifting the chassis.
• Remove all IFMs, power supplies, fans, and compute nodes from the chassis before lifting.
• Ensure that your footing is solid, and the weight of the system is evenly distributed between your feet.
• If you must lift an empty chassis, do not attempt this alone. Get assistance from at least one other person.
Installation Guidelines
When installing the chassis, follow these guidelines:
• Plan your site configuration and prepare the site before installing the chassis. See
• Record the information listed in
• Ensure that there is adequate space around the chassis to allow for servicing the chassis and for airflow.
• Ensure that the air-conditioning meets the heat dissipation requirements listed in
• Ensure that the cabinet or rack meets the requirements listed in
• Ensure that the site power meets the power requirements listed in
• Ensure that circuits are sized according to local and national codes. For North America, the power supply

We recommend that you use a UPS to protect the UCS system. Using an unprotected supply exposes
you to a risk of system failure due to input supply voltage variations or failures.
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 due to fluctuating data
traffic patterns.
