27InRow RD Fluid Cooled Installation

A-Link connections

The A-Link bus connection allows multiple InRow RDs (up to twelve) to communicate with one

another. Only one InRow RD must be defined through the display interface; other InRow RDs are

numbered automatically.

To enable the InRow RDs to work as a group, link them using the supplied cables or CAT-5 cables with

RJ-45 connectors. A terminator (150 Ohm, 1/4 W) is installed in the A-Link port, and must remain

inserted into the A-Link ports of the first and final InRow RDs only.

The maximum wire length for the entire group may not exceed 1,000 m (3,280 ft).
