Page 2: Abstract
Abstract High-density server installations involve an increasing amount of power and data cables within each rack. Mismanagement of cable assemblies can lead to poor system performance, difficult maintenance, unnecessary downtime, and even safety hazards. This paper describes proper methods and recommended techniques and products for safe and effective cable management. Introduction The trend in high performance computing (HPC) data centers is to implement high-density systems that make the most of available facility space. -
Page 3: Cable Routing Guidelines
Cable routing guidelines To minimize maintenance, safety, and performance issues, routing of power and data cables should be in accordance with the following guidelines. Separation of power and data cables Cables in close proximity to each other, especially those oriented in parallel or in loops, can create electromagnetic interference (EMI) through induction. -
Page 4: Securing Power Cables And Connectors
Securing power cables and connectors Power cables and connectors should receive extra care during installation, since loose cables or connectors can result in loss of power and unscheduled downtime. A loose power connector can create high contact resistance that can result in arcing and a fire hazard. HP power distribution products are often supplied with cable retaining clips or clamps (Figure 2), and HP strongly advises using these accessories when they are provided. -
Page 5: Thermal Issues With Cable Routing
• Use cable routing accessories designed to maintain and secure cable. • Leave enough slack in cables for operation of articulated arms and rail slides. Since actual conductor size and type vary among types of cables, the bend radius rule can differ among cable types. -
Page 6: Routing Network Cable
• Do not allow other cables or components to exert tension on fiber optic cables, which can be easily crushed or damaged. • Avoid routing fiber optic cable around chassis and cabinet corners. If this is unavoidable, protect the cable. Routing network cable Network interconnects can involve a large amount of cabling due to the component/data path redundancy required to meet high availability goals. -
