AvoidUPS types that use ferroresonant technology.These UPS types can become unstable with systems
suchas the Cisco UCS, which can have substantial current draw fluctuations due to fluctuating data
trafficpatterns.
•Ensurethat circuits are sized according to local and national codes. For North America, the power supply
requiresa 20 Acircuit.
Toprevent loss of input power, ensure that the total maximum loads on the circuits supplying power to
thechassis are within the current ratings for the wiring and breakers.
•Usethe following torque values when installing the chassis:
◦10-32screws: 20 in-lb
Required Equipment
Beforeyou begin the installation, ensure that you have the following items:
•Number1 and number2 Phillips-head screwdrivers with torque measuring capabilities
•Tapemeasure and level
•ESDwrist strap or othergrounding device
•Antistaticmat or antistaticfoam
Unpacking and Inspecting the Chassis
Whenhandling chassis components, wear an ESD strap and handle modules by the carrier edges only.Caution
Keepthe shipping container in case the chassis requires shipping in the future.Tip
Thechassis is thoroughly inspected before shipment. If any damage occurred during transportation or any
itemsare missing,contact your customerservice representative immediately.

•Anyprinted documentation
•Tool-lessrack-mount kit (N20-CRMK2=)—mounting rails can be installed in a rack without the use of
