Product questions & answers

What do P2C and C2P mean?

P2C moves air from the power side toward the connectors. C2P moves air from the connectors toward the power side. Select the direction specified for the exact switch configuration.

Can I select a replacement by appearance or wattage alone?

Use the manufacturer replacement-parts table for the complete switch model and order code. Matching dimensions, connector shape or PSU wattage alone does not establish compatibility.

Where should I check the replacement procedure?

Use the hardware manual for the exact chassis and component. Treat the replacement-parts list as ordering guidance; it does not replace the installation, airflow and safety instructions.

Does a power supply listing prove the required power cord is included?

Check the exact ordering row and quote. Some PSU rows explicitly include a cord; the Q3400-RA system ordering row explicitly excludes power cords. Cord region and electrical ratings still need checking.

Describe what you need. You can start without a confirmed quantity or host model.
