Moving Server Chassis
A fully configured chassis is very heavy! Be aware of its weight, and follow these guidelines:
Do not try to lift the chassis without mechanical assistance! The chassis weighs 400 lbs (181.43 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.
Caution
• 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.
Lift the system slowly, keeping your back straight. Lift with your legs, not with your back. Bend at the
knees, not at the waist.
Installation Guidelines
When installing the chassis, follow these guidelines:
• Plan your site configuration and prepare the site before installing the chassis. See Site Planning and
Maintenance Records for the recommended site planning tasks. For details, see the Cisco UCS Site
Preparation Guide.
• Record the information listed in Site Planning and Maintenance Records as you install and configure the
chassis.
• 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 Technical Specifications
• Ensure that the cabinet or rack meets the requirements listed in Rack Requirements, on page 2.
Jumper power cords are available for use in a rack. See Specifications for the
Cisco UCS X9508 Chassis Power Supply Units.
Note
• Ensure that the site power meets the power requirements listed in Technical Specifications. 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.
• Ensure that circuits are sized according to local and national codes. For North America, the power supply
requires a 20 A circuit.
To prevent loss of input power, ensure that the total maximum loads on the circuits supplying power to
the chassis are within the current ratings for the wiring and breakers.
