Power cabling with extension bars
Fixed-cord extension bars enable you to reduce traditional power cabling with the following methods:
• Eliminating standard-length power cords for each server power supply
• Aggregating server cabling into fewer PDU connections
The following figure shows the back of a fully-configured 42U rack with different types of scalable system
servers. The top half of the rack is configured for servers with two power supplies, while the bottom half of the
rack is configured for servers with a single power supply. Newer extension bars may have seven cords per
bar.
