Description

The Liebert MultiLink Cable Adapter Kit has two adapters designed for cable connections from a MultiLink

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.
