Professional FAQs

• What is the primary function of this expander cable?

It extends the Quantum backplane, allowing you to add a secondary rack of I/O or specialty modules located away from the main CPU rack, thereby increasing system capacity.

• Can I daisy-chain multiple racks using this cable?

No, this is a point-to-point cable designed to connect one expansion rack directly to a master rack. For more complex topologies, you must consult the Quantum system architecture guide.

• Are the connectors keyed to prevent incorrect installation?

Yes, the PROFIBUS connectors have a specific orientation and locking mechanism. This design prevents accidental mis-mating and ensures a secure, correct connection every time.

• Is the 2-meter length sufficient for most panel layouts?

In our experience, the 2-meter length is ideal for connecting racks within the same control cabinet or between adjacent enclosures. For longer runs, you may need to reconsider rack placement.

• How does this cable differ from a standard communication cable?

This is a specialized backplane expander that carries both high-speed data and power for the remote rack's modules. A standard network cable only handles data communication.
