Installation Instructions
Description
The Liebert MultiLink Cable Adapter Kit has two adapters designed for cable connections from a MultiLink
computer to a UPS or to a multiplexer such as the IntelliRack. These DB9-to-RJ45 adapters are used at
either end of an RJ45 straight-through cable, as described in these instructions.
This kit has the following components:
• DB9M - RJ45F adapter, part number ML-ADP-03
• DB9F - RJ45F adapter, part number ML-ADP-04
These instructions describe how to connect the adapters and an RJ45 cable.
Step 3
also provides information
to make a longer RJ45 cable, if needed.
Connecting Adapters
1. Connect the adapter labeled
ML-ADP-04
to the serial communication port on the
MultiLink computer.
2. Connect the other adapter (
