Chapter 4. Setting up your 5079 Expansion Unit
This chapter describes how to set up your 5079 Expansion Unit. If you are setting
up a 5074 Expansion Unit go, to Chapter 2, "Setting up your 5074 expansion unit"
If you have not powered down your system unit, go to "Powering down your
iSeries system unit" on page 6. Once you have powered down your system unit,
return here.
Removing the covers
See Appendix A, "Removing the back covers" on page 31 if you need help
removing the covers from your expansion units or system unit.
Connector locations
See Appendix B, "Connector Locations" on page 35 if you need help finding the
connectors on your expansion units or system unit.
Systems with migration units or 9079 Expansion Units
If your system unit has a migration unit or 9079 Expansion Unit, read Appendix D,
"Cabling rules for systems with a migration unit or the 9079 and 9094 expansion
unit" on page 45 before you proceed.
Connecting your 5079 directly to your system unit
Use the procedure below to connect your 5079 to your system unit.
Your 5079 consists of two independent 5074 Expansion Units in a single frame.
This procedure refers to the upper 5079 as 5079–002 and the lower 5074 as
5079–001.
You can set up 5079–002 and 5079–001 to your system unit on two separate HSL
loops if you have enough HSL cables and HSL connectors. Follow the steps in
"Connecting your 5074 directly to your system unit" on page 9 for each expansion
unit.
Refer to Figure 12 on page 20 and Figure 13 on page 20 before you start.
Note: This note only applies if your system unit is an iSeries server 830. Connect

on page 9.
HSL loops to the 830 in this order:
1. B0 and B1
2. C0 and C1
3. D0 and D1
4. A0 and A1
Connect HSL loops A0 and A1 only after the other three sets of HSL
connectors are used.
