Power Cabling With Y-Cables - HP ProLiant SL6500 Manual

Power cabling with Y-cables

For servers with 1200-W power supplies, Y-cables are specialized power cords that connect two power
supplies to a single C19 PDU outlet. Y-cables eliminate the need for extension bars (power strips) and can
provide lower cost, easier installation, and less clutter in the rack.
The following figure shows the side and 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 1200-W power supplies, while the
bottom half of the rack is configured for servers with one 1200-W power supply. The PDUs shown are
3-phase PDUs.
For illustration purposes only, the right rear rack column is removed to show cable routing.
