HP CX 6300 Installation And Getting Started Manual page 31

When using a DC power supply, the unit should be installed in a restricted access location. Only trained and
qualified personnel should be allowed to install, replace, or service this equipment.
Ensure that the DC cable is disconnected from the DC power source before proceeding with the installation.
1. Ensure that the correct DC cable is used for the power supply being installed.
a. Included DC cable HPPN 5400-3519 for JL758A (8AWG cable with Ring lugs).
b. Included DC cable HPPN 5400-3521 for JL757A (12AWG cable with Ring lugs).
2. Organize and tie the cable. The DC cable needs to be strain-relieved by tying securely it to a fixed structure
or rack. NOTE: Do not tie the DC cables to the power supply fan handle as it is not designed to take the
weight of the cables.
Ensure that the DC cable does not obstruct or block the air flow of the power supply fan.
