Chapter 3. Connecting Your 5075 To Another Expansion Unit; Connecting Your 5075 To The Beginning Of A Loop - IBM 5075 Setting Up

Chapter 3. Connecting your 5075 to another expansion unit

This section only applies to the AS/400e server 820. If your system unit is an
AS/400e server 270, you can connect only one 5075. If your system unit is an
AS/400e server 820, you can connect up to five expansion units in one loop. This
section describes how to connect your 5075 expansion unit in a loop with other
expansion units. You can only connect your 5075 with other expansion units that
have HSL hardware.
When you connect your 5075 to a loop, there are three possible locations in the
loop that it can go. The procedures below contain instructions for the three
possible locations:
v "Connecting your 5075 to the beginning of a loop".
v "Connecting your 5075 to the middle of a loop" on page 11.
v "Connecting your 5075 to the end of a loop" on page 12.
Follow the procedure that best matches your system configuration.
Make sure that you have powered down your system unit before you begin. See
"Powering down your system unit" on page 3 for instructions.
See "Appendix B. Connector Locations" on page 23 if you need help finding the
connectors on your expansion units or system unit.
If your 820 has a 503x Migration Unit connected to it, read "Appendix D. Cabling
rules for systems with a 503x Migration Unit" on page 29 before you proceed.
If you encounter difficulties during the installation, contact your authorized dealer
or service provider.
Connecting to a 503x migration unit
If your system unit has a 503x Migration Unit read "Appendix D. Cabling rules for
systems with a 503x Migration Unit" on page 29 before you proceed.

Connecting your 5075 to the beginning of a loop

Use this procedure to connect your 5075 in the first position in a loop of expansion
units. In this procedure you will connect your 5075 between your system unit and
the expansion unit which is currently in the first position. These instructions refer
to the expansion unit which is currently in the first position as unit X as is shown
in Figure 7 on page 10 and Figure 8 on page 10.
