Cabling and Adapter Usage

This page addresses Nodegrid Serial Console cabling and adapter usage in data center environments.

Due to the lack of industry standards for RS-232 console ports and cabling, we are providing information for adapting the NSC to your heterogeneous, multi-vendor infrastructure devices. You may use the serial port pin-out information here to make your own cabling.
