Chapter 1. Preparing to set up your 5074 or 5079 Expansion
Unit
This chapter explains what you need to do before you set up your 5074 or 5079
Expansion Unit. This includes the following tasks:
1. Unpack your expansion unit (refer to the instructions for unpacking that came
with your expansion unit).
2. Plan layouts for your cables.
3. Power down your system unit.
Before you begin the installation process, carefully plan where you will install your
new expansion unit. You should consider several factors that include size, security,
and environmental factors. Before you set up your new expansion unit, refer to the
