Chapter 1. Preparing to set up your 5075 Expansion Unit
This chapter explains what you need to do before you set up your 5075 Expansion
Unit. This includes the following tasks:
1. Unpack your 5075 (refer to the instructions for unpacking that came with your
2. Plan layouts for your cables.
3. Power down your system unit.
4. Install the 7002 cable (if needed).
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
AS/400 Site Preparation guide at the Technical Studio web site:

Hardware requirements
You can connect your 5075 directly to your system unit if it is an AS/400e server
270 or 820. If your system unit is an AS/400e server 820, you also may connect
your 5075 to another expansion unit.
If you are connecting your 5075 directly to your system unit, you need to have
these prerequisites:
v An unused system power control network (SPCN) connector.
v An unused high speed link (HSL) connector.
If you are connecting your 5075 to another expansion unit, your 820 can have a
maximum of five expansion units in a loop.
Planning your cable layout
When you decide where to place your cables, do the following:
v Refer to the AS/400 Site Preparation guide or web site.
v Follow your site plan.
v Avoid creating a safety hazard.
v Avoid damaging the cable.
v Avoid placing cables parallel to high-voltage lines.
Identifying HSL and SPCN Cables
Use the following tables to identify your High Speed link (HSL) and System Power
Control Network cables. Your system uses HSL cables to communicate with your
5075. SPCN cables are used to control power to your 5075.
Depending on your requirements, you might not have every HSL or SPCN cable
listed below.
