6. Cable the disk drive enclosure to the server as follows:
a.
Confirm that all adapters that you need to connect to the 58/86 disk drive enclosure have been
installed in the system. If the adapters have not been installed, complete the adapter installation
procedure for your system before continuing with this task.
b. If the server requires an internal cable to be installed to produce an external SAS port for
connection with the 58/86 disk drive enclosure, confirm that the installation has been performed.
Review the following list of systems that require the installation of an external SAS port, and then
complete the action for your system, if required:
Remember: When installing or confirming the use of an external SAS port, record the location of
the external SAS port on the server. Later in this procedure, you are instructed to install the
external SAS cable to this server connector location.

c. Locate the connection for each adapter for which you are using an external SAS cable to connect
the 58/86. Adapter cables attach to ports at the rear of the servers in which the adapters are
installed. To identify the SAS port location for the server in your configuration, see “Connector
locations” on page 15.
Note: The configuration figures in step 6d use adapter cards to represent the external server
connections. The adapter card can represent one of the following connection types:
v
The external port of an adapter that you confirmed in step 6a.
v
The external port of an internal adapter cable that you confirmed in step 6b.
d.
Choose one of the following options to cable the SAS adapter.
Note: Adapters are cabled to the 58/86 by using ports at the rear of the enclosure. To learn about
the enclosure ports that are used in the following options, see “Model 58/86 connector locations”
on page 22.
v
To perform a connection of one 58/86 disk drive enclosure to a single SAS adapter by using a
YO cable, go to step 6e on page 10.
v
To perform a connection of two 58/86 disk drive enclosures to a single SAS adapter by using
YO cables, where each enclosure can be attached to an additional 58/86 disk drive enclosure by
using an EE cable, go to step 6f on page 10.
v
To perform a connection of two 58/86 disk drive enclosures to a SAS adapter pair by using X
cables, where each enclosure can be attached to an additional 58/86 disk drive enclosure by
using an EE cable, go to step 6g on page 11.
v
To perform a connection of one 58/86 disk drive enclosure by using a YI cable to a system with
support for a single SAS drawer, go to step 6h on page 12.
