DC wiring must meet your local codes and regulations, we recommend using a licensed local electrician to install the DC wiring needed.
The AC power supply connector on the blade server chassis is an IEC 320 C20 socket. The power cord that you use to connect the blade server power supply units to an AC power outlet will have an IEC 320 C19 plug on one end a plug on the other end that conforms to the AC power outlet specifications for your country. To determine which cord to order for your blade server chassis power supply units, see Table 3-11. When you determine which power cord you need to order, you can verify that its plugs conform to the power outlets for your facility by clicking on its reference link.

Each power supply has a separate power cord. Standard power cords or jumper power cords are available for connection to a power distribution unit having IEC 60320 C19 outlet receptacles. The jumper power cords, for use in cabinets, are available as an optional alternative to the standard power cords.
The standard power cords have an IEC C19 connector on the end that plugs into the power supplies. The optional jumper power cords have an IEC C19 connector on the end that plugs into the power supplies, and an IEC C20 connector on the end that plugs into an IEC C19 outlet receptacle.
Note
Only the regular power cords or jumper power cords provided with the chassis are supported.

Power Supply Configuration Modes
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:
•
http://www.cisco.com/en/US/docs/unified_computing/ucs/hw/chassis/install/overview.html#wp1245307
Blade Server Chassis and Fabric Interconnect Clearances
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.
Facility Cooling Requirements
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 6248UP Fabric Interconnect dissipates up to 1998 BTUs per hour
•
Cisco UCS 5108 Blade Server Chassis dissipates up to 1364 BTUs per hour
•
Each Cisco B200 or B230 Blade Server dissipates up to 1347 BTUs per hour
Chassis Airflow
The Cisco UCS 5108 chassis and the Cisco UCS 6100 Series Fabric Interconnect 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 Figure 3-34, 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.
