Cabling guidelines Cabling guidelines
The cable colors in the cabling diagrams used in this chapter are for illustration purposes only. Most of the system cables are black.
Observe the following guidelines when working with system cables.
Before connecting cables Before connecting cables
Note the port labels on the PCA components. Not all of these components are used by all systems:
System board ports
Drive and power supply backplane ports
Expansion card ports (controllers, adapters, expanders, risers, and similar boards)
Note the label near each cable connector. This label indicates the destination port for the cable connector.
Some data cables are pre-bent. Do not unbend or manipulate the cables.
To prevent mechanical damage or depositing oil that is present on your hands, and other contamination, do not touch the ends of
the connectors.
When connecting cables When connecting cables
Before connecting a cable to a port, lay the cable in place to verify the length of the cable.
Use the internal cable management features to properly route and secure the cables.
When routing cables, be sure that the cables are not in a position where they can be pinched or crimped.
Avoid tight bend radii to prevent damaging the internal wires of a power cord or a server cable. Never bend power cords and server
cables tight enough to cause a crease in the sheathing.
Make sure that the excess length of cables are properly secured to avoid excess bends, interference issues, and airflow restriction.
To prevent component damage and potential signal interference, make sure that all cables are in their appropriate routing position
before installing a new component and before closing up the system after hardware installation/maintenance.
When disconnecting cables When disconnecting cables
Grip the body of the cable connector. Do not pull on the cable itself because this action can damage the internal wires of the cable or
the pins on the port.
If a cable does not disconnect easily, check for any release latch that must be pressed to disconnect the cable.
