NetShelter SX Cable Management Guidelines
Cable management is an ever increasing concern at the equipment and enclosure level in the data center. The move to higher density servers and switch applications has increased the cable quantity for both data and power. In addition, higher speed data cables are becoming larger in diameter. These factors are pushing the usable space within the enclosure to the limits. Poor cable management causes congestion and restricts airflow. Proper cable management eliminates congestion and allows air to flow unobstructed through the equipment.

Using APC InfraStruXure Three Phase Whips and RM PDUs for Non-linear Loads
Consulting Engineers and customers frequently express concern about the acceptability of three phase, 4-wire whips and rack-mount PDUs that are used to distribute InfraStruXure power in a nonlinear load environment. APC is frequently challenged to supply 200% rated neutral conductors. APC conducted extensive testing and demonstrated beyond any doubt that the whips and rack-mount PDUs can be safely used in the worst nonlinear load environment. This application note describes the test methods and provides the test results that support that conclusion.

Success in deploying these servers – there are five basic strategies – requires an understanding of several inputs, including the business needs driving the deployment, user preferences, blade requirements, and constraints. This Application Note considers these inputs, and guides the reader to (1) select the best deployment method from the five basic methods, (2) choose the appropriate rack, cooling, power, and management solutions, and (3) apply these solutions to fit individual needs.

PowerChute® Network Shutdown with more than 50 Computers connected to one UPS
PowerChute® Network Shutdown works with the UPS Network Management Card to provide graceful shutdown of computers powered by a UPS. The number of computers is limited only by the power capacity of the UPS; however, if you wish to have more than 50 computers powered by one UPS, some consideration must be given to the system configuration. Knowledge of the communication between PowerChute and the UPS Network Management Card is necessary.

Hot Aisle Containment Application Guidelines and Approved Configurations
The Hot Aisle Containment System (HACS) is a modular ceiling panel and door system for use in isolating the supply and return air between an APC NetShelter rack and an APC InRow® cooling solution. The containment system is designed to create a separate environment for air distribution in order to prevent mixing of hot and cold air streams, resulting in a more predictable cooling pattern. The modular design and ability to retrofit to an existing Netshelter rack enables medium to high density racks to be cooled in an autonomous environment without overcooling the room.
