The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

DC wiring must meet your local codes and regulations, we recommend using a licensed local electrician to install the DC wiring needed.
To determine the number of power supply units needed for the blade server, remember that each single slot server is budgeted a max 550 W and each full width server is budgeted a max 1100 W. For a more detailed estimate, contact Cisco Sales.
For information about supported power cords, see the Cisco UCS 5108 Server Chassis Installation Guide.
One power supply is required for basic operation, two power supplies provides redundancy.
For information about supported power cords and plugs, see the Cisco UCS 6100 Series Fabric Interconnect Hardware Installation Guide.

If a replacement DC connector is needed, a Phoenix Contact part number PC 5/ 2-STF-7,62, order number 1975697 or direct equivalent. Connector information is available at: http://eshop.phoenixcontact.de/phoenix/treeViewClick.do?UID=1975697 |

You can configure power modes to either use the combined power provided by the installed power supply units or to provide power redundancy when there is a power outage.
The power supplies are all operated in parallel output. You should connect two separate input sources (grids) to have the highest level of availability (grid redundancy). The system will operate on two power supplies (2+2 redundancy) for the Cisco UCS 5108 blade server chassis and one power supply (1+1 redundancy) for the Cisco UCS 6100 Series Fabric Interconnect. More detail is at:
You must provide adequate clearance for installing the chassis, replacing modules, and allowing airflow to and from the equipment. The blade server chassis and fabric interconnect require at least 36.0 inches (91.4 cm) of clearance in front to replace a blade or a fabric interconnect. They also require at least 16 inches (40.6 cm) of clearance in back of the equipment to install and replace their components. No side clearance is required because there are no components to replace on the sides of the chassis. No clearance or empty rack units are required between the equipment.
Note | If you need more space for the mechanical lift, include the additional space with the clearance for the front of the chassis. |
For the blade server chassis and fabric interconnect, the clearances for installation and replacement of components is adequate for the cooling airflow. Side clearance is not needed for installation, replacement, or airflow.
The Cisco UCS components dissipate considerable power and generate considerable heat. The major components require the following heat dissipation:
Cisco UCS 6120XP Fabric Interconnect dissipates up to 1534 BTUs per hour
Cisco UCS 6140XP Fabric Interconnect dissipates up to 2561 BTUs per hour
Cisco UCS 6248 UP Fabric Interconnect dissipates up to 1998 BTUs per hour
Cisco UCS 6296 UP Fabric Interconnect dissipates up to 3163 BTUs per hour
Cisco UCS 5108 Blade Server Chassis dissipates up to 1364 BTUs per hour
Each half width Blade Server dissipates approximately 1350 BTUs per hour
Each full width Blade Server dissipates approximately 2700 BTUs per hour
The Cisco UCS 5108 chassis and the Cisco UCS Fabric Interconnects each use front-to-back airflow for cooling, and both components are designed to work in a hot-aisle/cold-aisle environment.
Cable management can be an important factor in preventing overheating issues. In the figure below, the "before" illustration shows cables blocking the rear of the chassis, and preventing the fans from exhausting warm air from the chassis. This situation causes failed DIMMs in the blade servers, and seemingly random server shutdowns when internal temperatures exceed specification. Use cable ties and other wiring practices to keep the rear of the chassis unobstructed as shown in the "after" illustration.
