Black Box EHN485-0020 KVM CPU Cable - VGA, USB, Coax, 20-FT
Overview
The Black Box EHN485-0020 is a 20-foot KVM CPU cable designed to connect a server's VGA video, USB keyboard/mouse, and coax serial ports to a compatible KVM switch. This cable ensures reliable signal integrity for remote server management in environments where direct physical access is impractical or undesirable. Its 20-foot length provides sufficient reach for typical rack deployments without excessive cable slack.
Compatibility
This cable is engineered for use with KVM switches that feature VGA, USB Type-A (for keyboard/mouse), and Coax (for serial data) connectors on the CPU side. It is designed to interface with servers and computers requiring these specific connection types for KVM extension. Verify your KVM switch's CPU port configuration against the cable's connectors (VGA male, USB Type-A male, Coax male) to ensure a match.
Installation Notes
Connect the VGA, USB, and Coax connectors to the corresponding ports on the target server or computer. Then, connect the other end of the cable to the CPU ports on your Black Box KVM switch. Ensure all connections are securely seated to prevent signal loss or intermittent connectivity. The cable is rated for standard indoor IT environments.
